Storage and Operation Conditions
1. The performance of chip monolithic ceramic capacitors may be affected by the storage conditions.
1-1. Store the capacitors in the following conditions:Room Temperature of +5°C to +40°C and a Relative Humidity
of 20% to 70%.
(1) Sunlight, dust, rapid temperature changes, corrosive gas atmosphere, or high temperature and humidity
conditions during storage may affect solderability and packaging performance. Therefore, please maintain
the storage temperature and humidity. Use the product within six months, as prolonged storage may cause
oxidation of the electrodes.
(2) Please confirm solderability before using after six months. Store the capacitors without opening the original bag.
Even if the storage period is short, do not exceed the specified atmospheric conditions.
1-2. Corrosive gas can react with the termination(external) electrodes or lead wires of capacitors, and result
in poor solderability. Do not store the capacitors in an atmosphere consisting of corrosive gas
(e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas, etc.).
1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused
by direct sunlight on the terminal electrodes and/or the resin/epoxy coatings, the solderability and electrical
performance may deteriorate. Do not store capacitors under direct sunlight or in high humidity conditions.

1. Temperature Dependent Characteristics
1. The electrical characteristics of a capacitor can change with temperature.
1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature changes.
The following actions are recommended in order to ensure suitable capacitance values.
(1) Select a suitable capacitance for the operating temperature range.
(2)
The capacitance may change within the rated temperature. When you use a high dielectric constant type
capacitor in a circuit that needs a tight (narrow) capacitance tolerance (e.g., a time-constant circuit),
please carefully consider the temperature characteristics, and carefully confirm the various characteristics
in actual use conditions and the actual system.
2. Measurement of Capacitance
1. Measure capacitance with the voltage and frequency specified in the product specifications.
1-1.
The output voltage of the measuring equipment may decrease occasionally when capacitance is high.
Please confirm whether a prescribed measured voltage is impressed to the capacitor.
1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.
Please consider the AC voltage characteristics when selecting a capacitor to be used in an AC circuit.
3. Applied Voltage
1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.
1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.

Caution
4. Type of Applied Voltage and Self-heating Temperature
1. Confirm the operating conditions to make sure that no large current is flowing into the capacitor due to the continuous
application of an AC voltage or pulse voltage. When a DC rated voltage product is used in an AC voltage circuit or a
pulse voltage circuit, the AC current or pulse current will flow into the capacitor; therefore check the self-heating condition.
Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits of the
operating temperature, including the rise in temperature due to self-heating. When the capacitor is used with a
high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.
<Applicable to Rated Voltage of less than DC100V>
1-1.
The load should be contained to the level such that when measuring at atmospheric temperature of 25, the product's
self-heating remains below 20 and the surface temperature of the capacitor in the actual circuit remains within the
maximum operating temperature.
<Applicable to Temperature Characteristic X7R, X7T beyond Rated Voltage of DC200V>
1-2. The load should be contained so that the self-heating of the capacitor body remains below 20°C, when measuring at
an ambient temperature of 25°C. In addition, use a K thermocouple of φ0.1mm with less heat capacity when
measuring, and measure in a condition where there is no effect from the radiant heat of other components or air flow
caused by convection. Excessive generation of heat may cause deterioration of the characteristics and reliability of the
capacitor. (Absolutely do not perform measurements while the cooling fan is operating, as an accurate measurement
may not be performed.)
5. DC Voltage and AC Voltage Characteristics
1. The capacitance value of a high dielectric constant type capacitor changes depending on the DC voltage applied.
Please consider the DC voltage characteristics when a capacitor is selected for use in a DC circuit.
1-1. The capacitance of ceramic capacitors may change sharply depending on the applied voltage (see figure).
Please confirm the following in order to secure the capacitance.
(1) Determine whether the capacitance change caused by the applied voltage is within the allowed range.
(2) In the DC voltage characteristics, the rate of capacitance change becomes larger as voltage increases, even if the
applied voltage is below the rated voltage. When a high dielectric constant type capacitor is used in a circuit that
requires a tight (narrow) capacitance tolerance (e.g., a time constant circuit), please carefully consider the voltage
characteristics, and confirm the various characteristics in actual operating conditions in an actual system.
2. The capacitance values of high dielectric constant type capacitors changes depending on the AC voltage applied.
Please consider the AC voltage characteristics when selecting a capacitor to be used in an AC circuit.
6. Capacitance Aging
1. The high dielectric constant type capacitors have the characteristic in which the capacitance value decreases with the
passage of time. When you use high dielectric constant type capacitors in a circuit that needs a tight (narrow) capacitance
tolerance (e.g., a time-constant circuit), please carefully consider the characteristics of these capacitors, such as their
aging, voltage, and temperature characteristics. In addition, check capacitors using your actual appliances at the intended
environment and operating conditions.
7. Vibration and Shock
1. Please confirm the kind of vibration and/or shock, its condition, and any generation of resonance.
Please mount the capacitor so as not to generate resonance, and do not allow any impact on the terminals.
2.
Mechanical shock due to being dropped may cause damage or a crack in the dielectric material of the capacitor.
Do not use a dropped capacitor because the quality and reliability may be deteriorated.
3. When printed circuit boards are piled up or handled, the corner of another printed circuit board should not be allowed
to hit the capacitor, in order to avoid a crack or other damage to the capacitor.

Soldering and Mounting
1.
Mounting Position
1. Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing
or bending the printed circuit board.
1-1. Choose a mounting position that minimizes the stress imposed on the chip during flexing or bending of the board.
[Component Direction]
Locate chip horizontal to the direction in which stress acts.
[Chip Mounting Close to Board Separation Point]
It is effective to implement the following measures, to reduce stress in separating the board. It is best to implement all
of the following three measures; however, implement as many measures as possible to reduce stress.
[Mounting Capacitors Near Screw Holes]
When a capacitor is mounted near a screw hole, it may be affected by the board deflection that occurs during the
tightening of the screw. Mount the capacitor in a position as far away from the screw holes as possible.
2. Information before Mounting
1. Do not re-use capacitors that were removed from the equipment.
2. Confirm capacitance characteristics under actual applied voltage.
3. Confirm the mechanical stress under actual process and equipment use.
4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly.
5.
Prior to use, confirm the solderability of capacitors that were in long-term storage.
6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.
7. The use of Sn-Zn based solder will deteriorate the reliability of the MLCC.
Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance.
8. We have also produced a DVD which shows a summary of our opinions, regarding the precautions for mounting.

Caution
2.
Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent the nozzle from moving
moving smoothly. This imposes greater force upon the chip during mounting, causing cracked chips. Also, the locating
claw, when worn out, imposes uneven forces on the chip when positioning, causing cracked chips.
The suction nozzle and the locating claw must be maintained, checked, and replaced periodically.
4-1. Reflow Soldering
1. When sudden heat is applied to the components, the [Standard Conditions for Reflow Soldering]
mechanical strength of the components will decrease
because a sudden temperature change causes deformation
inside the components. In order to prevent mechanical damage
to the components, preheating is required for both the
components and the PCB. Preheating conditions are shown
in table 1. It is required to keep the temperature differential
between the solder and the components surface (ΔT) as small
as possible.
2. Solderability of tin plating termination chips might be
deteriorated when a low temperature soldering profile where
the peak solder temperature is below the melting point of tin
is used. Please confirm the solderability of tin plated
termination chips before use.
3. When components are immersed in solvent after mounting,
be sure to maintain the temperature difference (ΔT) between
the component and the solvent within the range shown in table 1.
Table 1
Recommended Conditions
[Allowable Reflow Soldering Temperature and Time]
Pb-Sn Solder: Sn-37Pb
Lead Free Solder: Sn-3.0Ag-0.5Cu
4. Optimum Solder Amount for Reflow Soldering
4-1. If solder paste is excessive, solder between a chip and a
metal terminal melts. This causes the chip to move and
come off.
4-2.
If solder paste is too little, it causes a lack of adhesive
strength on the metal terminal and the capacitor comes off.
4-3. Please make sure that solder is smoothly applied higher
than 0.3mm and lower than the level of the bottom of the
chip.
Make sure not to impose any abnormal mechanical shocks to the PCB.
4-2.

Caution
4-3. Correction of Soldered Portion
1. For the shape of the soldering iron tip, refer to the figure
on the right.
2. Regarding the type of solder, use a wire diameter of
φ0.5mm or less (rosin core wire solder).
3. Apply the tip of the soldering iron against the lower end
of the metal terminal.
(1) In order to prevent cracking caused by sudden heating
of the ceramic device, do not touch the ceramic base
directly.
(2) In order to prevent deviations and dislocating of the
chip, do not touch the junction of the chip and the metal
terminal, and the metal portion on the outside directly.
4. The amount of solder for corrections by soldering iron,
should be lower than the height of the lower side of the chip.
5.
Washing
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken
solder joints. Take note not to vibrate PCBs.
6. Electrical Test on Printed Circuit Board
1. Confirm position of the backup pin or specific jig, when inspecting the electrical performance of a capacitor after
mounting on the printed circuit board.
1-1. Avoid bending the printed circuit board by the pressure of a test-probe, etc. The thrusting force of the test probe can
flex the PCB, resulting in cracked chips or open solder joints. Provide backup pins on the back side of the PCB
to prevent warping or flexing. Install backup pins as close to the capacitor as possible.
1-2. Avoid vibration of the board by shock when a test-probe contacts a printed circuit board.
[Not Recommended] [Recommended]
7.
Printed Circuit Board Cropping
1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that causes bending
or twisting the board.
1-1. In cropping the board, the stress as shown at right may cause the capacitor to crack. Cracked capacitors may cause
deterioration of the insulation resistance, and result in a short. Avoid this type of stress to a capacitor.

Caution
2.
Check the cropping method for the printed circuit board in advance.
2-1. Printed circuit board cropping shall be carried out by using a jig or an apparatus (Disk separator, router type separator,
etc.) to prevent the mechanical stress that can occur to the board.
* When a board separation jig or disk separator is used, if the following precautions are not observed, a large board deflection stress will occur and the capacitors
may crack. Use router type separator if at all possible.
(1) Example of a suitable jig
[In the case of Single-side Mounting]
An outline of the board separation jig is shown as follows. Recommended example: Stress on the component
mounting position can be minimized by holding the portion close to the jig, and bend in the direction towards
the side where the capacitors are mounted. Not recommended example: The risk of cracks occurring in the
capacitors increases due to large stress being applied to the component mounting position, if the portion away
from the jig is held and bent in the direction opposite the side where the capacitors are mounted.
[Outline of Jig]
[In the case of Double-sided Mounting]
Since components are mounted on both sides of the board, the risk of cracks occurring can not be avoided with the
above method. Therefore, implement the following measures to prevent stress from being applied to the components.
(Measures)
Consider introducing a router type separator. If it is difficult to introduce a router type separator, implement
the following measures. (Refer to item 1. Mounting Position)
Mount the components at a right angle to the board separation surface.
When mounting components near the board separation point, add slits in the separation position
near the component.
Keep the mounting position of the components away from the board separation point.
(2) Example of a Disk Separator
An outline of a disk separator is shown as follows. As shown in the Principle of Operation, the top blade and bottom
blade are aligned with the V-grooves on the printed circuit board to separate the board. In the following case, board
deflection stress will be applied and cause cracks in the capacitors.
When the adjustment of the top and bottom blades are misaligned, such as deviating in the top-bottom, left-right
or front-rear directions
The angle of the V groove is too low, depth of the V groove is too shallow, or the V groove is misaligned
top-bottom IF V groove is too deep, it is possible to brake when you handle and carry it. Carefully design depth of
the V groove with consideration about strength of material of the printed circuit board.

Caution
(3) Example of Router Type Separator
The router type separator performs cutting by a router rotating at a high speed. Since the board does not bend in the
cutting process, stress on the board can be suppressed during board separation. When attaching or removing
boards to/from the router type separator, carefully handle the boards to prevent bending.
[Outline Drawing]
8. Assembly
1. Handling
If a board mounted with capacitors is held with one hand, the board may bend. Firmly hold the edges of the board with
both hands when handling. If a board mounted with capacitors is dropped, cracks may occur in the capacitors.
Do not use dropped boards, as there is a possibility that the quality of the capacitors may be impaired.
2. Attachment of Other Components
2-1. Mounting of Other Components
Pay attention to the following items, when mounting other
components on the back side of the board after capacitors
have been mounted on the opposite side. When the bottom
dead point of the suction nozzle is set too low, board deflection
stress may be applied to the capacitors on the back side
(bottom side), and cracks may occur in the capacitors.
After the board is straightened, set the bottom dead point
of the nozzle on the upper surface of the board.
Periodically check and adjust the bottom dead point.
2-2. Inserting Components with Leads into Boards
When inserting components (transformers, IC, etc.) into boards,
bending the board may cause cracks in the capacitors or
cracks in the solder. Pay attention to the following.
Increase the size of the holes to insert the leads, to reduce
the stress on the board during insertion.
Fix the board with backup pins or a dedicated jig before
insertion.
Support below the board so that the board does not bend.
When using multiple backup pins on the board, periodically
confirm that there is no difference in the height of each
backup pin.

1. The operating temperature limit depends on the capacitor.
1-1. Do not apply temperatures exceeding the upper operating temperature. It is necessary to select a capacitor with
a suitable rated temperature that will cover the operating temperature range. It is also necessary to consider
the temperature distribution in equipment and the seasonal temperature variable factor.
1-2. Consider the self-heating factor of the capacitor. The surface temperature of the capacitor shall be the upper
operating temperature or less when including the self-heating factors.
2. Atmosphere Surroundings (gaseous and liquid)
1. Restriction on the operating environment of capacitors.
1-1. Capacitors, when used in the above, unsuitable, operating environments may deteriorate due to the corrosion
of the terminations and the penetration of moisture into the capacitor.
1-2. The same phenomenon as the above may occur when the electrodes or terminals of the capacitor are subject
to moisture condensation.
1-3. The deterioration of characteristics and insulation resistance due to the oxidization or corrosion of terminal
electrodes may result in breakdown when the capacitor is exposed to corrosive or volatile gases or solvents
for long periods of time.
3. Piezo-electric Phenomenon
1. When using high dielectric constant type capacitors in AC or pulse circuits, the capacitor itself vibrates at specific
frequencies and noise may be generated. Moreover, when the mechanical vibration or shock is added to the capacitor,
noise may occur.
Soldering and Mounting
1.
PCB Design
1. Notice for Pattern Forms
1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted directly
on the substrate. They are also more sensitive to mechanical and thermal stresses than leaded components.
Excess solder fillet height can multiply these tresses and cause chip cracking. When designing substrates,
take land patterns and dimensions into consideration to eliminate the possibility of excess solder fillet height.
1-2. There is a possibility of chip cracking caused by PCB expansion/contraction with heat, because stress on a chip is
different depending on PCB material and structure. When the thermal expansion coefficient greatly differs between
the board used for mounting and the chip, it will cause cracking of the chip due to the thermal expansion and
contraction. When small size capacitors of 1005 size or less are mounted on a single-layered glass epoxy board,
it will also cause cracking of the chip for the same reason.

Notice
2. Land Dimensions
2-1. Chip capacitors can be cracked due to the stress of PCB
bending, etc. if the land area is larger than needed and
has an excess amount of solder. Please refer to the land
dimensions in the following table for reflow soldering.
Please confirm the suitable land dimension by evaluating
of the actual SET / PCB.
3. Board Design
When designing the board, keep in mind that the amount of strain which occurs will increase depending on the size
and material of the board.
4.
Washing
1. Please evaluate the capacitor using actual cleaning equipment and conditions to confirm the quality, and select the
solvent for cleaning.
2. Unsuitable cleaning solvent may leave residual flux or other foreign substances, causing deterioration of electrical
characteristics and the reliability of the capacitors.
3. Select the proper cleaning conditions.
3-1.
Improper cleaning conditions (excessive or insufficient) may result in deterioration of the performance of the capacitors.
5. Coating
1. A crack may be cause in the capacitor due to the stress of the thermal contraction of the resin during curing process. The
stress is affected by the amount of resin and curing contraction. Select a resin with low curing contraction. The difference
in the thermal expansion coefficient between a coating resin or a molding resin and the capacitor may cause the
destruction and deterioration of the capacitor such as a crack or peeling, and lead to the deterioration of insulation
resistance or dielectric breakdown. Select a resin for which the thermal expansion coefficient is as close to that of the
capacitor as possible. A silicone resin can be used as an under-coating to buffer against the stress.
2. Select a resin that is less hygroscopic. Using hygroscopic resins under high humidity conditions may cause
the deterioration of the insulation resistance of a capacitor. An epoxy resin can be used as a less hygroscopic resin.

1. Transportation
1. The performance of a capacitor may be affected by the conditions during transportation.
1-1. The capacitors shall be protected against excessive temperature, humidity, and mechanical force during
transportation.
(1) Climatic condition
low air temperature : -40
change of temperature air/air : -25/+25
low air pressure : 30kPa
change of air pressure : 6kPa/min.
(2) Mechanical condition
Transportation shall be done in such a way that the boxes are not deformed and forced are not directly passed
on to the inner packaging.
1-2. Do not apply excessive vibration, shock, or pressure to the capacitor.
(1) When excessive mechanical shock or pressure is applied to a capacitor, chipping or cracking may occur
in the ceramic body of the capacitor.
(2)
When the sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the surface
of the capacitor, the capacitor may crack and short-circuit.
1-3.
Do not use a capacitor to which excessive shock was applied by dropping, etc. A capacitor dropped accidentally
during processing may be damaged.
2. Characteristics Evaluation in the Actual System
1. Evaluate the capacitor in the actual system, to confirm that there is no problem with the performance and specification
values in a finished product before using.
2. Since a voltage dependency and temperature dependency exists in the capacitance of high dielectric type ceramic
capacitors, the capacitance may change depending on the operating conditions in the actual system. Therefore,
be sure to evaluate the various characteristics, such as the leakage current and noise absorptivity, which will affect
the capacitance value of the capacitor.
3. In addition, voltages exceeding the predetermined surge may be applied to the capacitor by the inductance in the actual
system. Evaluate the surge resistance in the actual system as required.
