Introduction
KEMET has developed a new type of tantalum capacitor
that replaces the solid manganese dioxide electrode with
a solid conductive polymer. This product is named the
KO-CAP for KEMET Organic Capacitor. The basic fami-
lies are the T520 and T530 series. A separate detail of
performance characteristics is presented here as there
are some differences between the polymer tantalums and
the standard
MnO2
types. Like all KEMET tantalum
chips, these series are 100% screened for all electrical
parameters: Capacitance @ 120 Hz, Dissipation Factor
(DF) @ 120 Hz, ESR @ 100 kHZ and DC Leakage. It is
also 100% surge current tested at full rated voltage
through a low impedance circuit. The advantages of the
polymer include very low ESR and elimination of the
potentially catastrophic failure mode that may occur with
standard tantalum capacitors in a high surge current
application. Although the natural KO-CAP series failure
mechanism is a short circuit, it does not exhibit an explo-
sive failure mode.
ELECTRICAL
1. Operating Temperature Range
-55ºC to +105ºC
Above 85ºC, the voltage rating is reduced linearly
from 1.0 x rated voltage to 0.8 x rated voltage at
105ºC.
2. Non-Operating Temperature Range
-55ºC to +105ºC
3. Capacitance and Tolerance
33µF to 1500µF
±20% Tolerance
Capacitance is measured at 120 Hz, up to 1.0 volt rms
maximum and up to 2.5V DC maximum. DC bias caus-
es only a small reduction in capacitance, up to about
2% when full rated voltage is applied. DC bias is not
commonly used for room temperature measurements
but is more commonly used when measuring at tem-
perature extremes.
Capacitance does decrease with increasing frequency,
but not nearly as much or as quickly as standard tanta-
lums. Figure 1 compares the frequency induced cap roll-
off between the KO-CAP and traditional MnO2 types.
Capacitance also increases with increasing tempera-
ture. See section 12 for temperature coefficients.
4. Voltage Ratings
2V-16V DC Rated Voltage
This is the maximum peak DC operating voltage
from -55ºC to +85ºC for continuous duty. Above
85ºC, this voltage is derated linearly to 0.8 times
the rated voltage for operation at 105ºC.
Surge Voltage Ratings
Surge voltage is the maximum voltage to which the
part can be subjected under transient conditions
including the sum of peak AC ripple, DC bias and
any transients. Surge voltage capability is demon-
strated by application of 1000 cycles of the relevant
voltage, at 25ºC, 85ºC or 105ºC. The parts are
charged through a 33 ohm resistor for 30 seconds
and then discharged through a 33 ohm resistor for
30 seconds for each cycle.

5. Reverse Voltage Rating & Polarity
Polymer tantalum capacitors are polar devices and
may be permanently damaged or destroyed if con-
nected in the wrong polarity. The positive terminal
is identified by a laser-marked stripe and may also
include a beveled edge. These capacitors will with-
stand a small degree of transient voltage reversal
for short periods as shown in the following table.
Please note that these parts may not be operated
continuously in reverse, even within these limits.
Table 2
Temperature Permissible Transient Reverse Voltage
25ºC 15% of Rated Voltage
55ºC 10% of Rated Voltage
85ºC 5% of Rated Voltage
105ºC 3% of Rated Voltage
6. DC Leakage Current
Because of the high conductivity of the polymer,
the KO-CAP family has higher leakage currents
than traditional MnO2 type Tantalum caps. The DC
Leakage limits at 25ºC are calculated as 0.1 x C x
V, where C is cap in µF and V is rated voltage in
Volts. Limits for all part numbers are listed in the
ratings tables.
DC Leakage current is the current that flows
through the capacitor dielectric after a five minute
charging period at rated voltage. Leakage is mea-
sured at 25ºC with full rated voltage applied to the
capacitor through a 1000 ohm resistor in series
with the capacitor.

COMPONENT PERFORMANCE CHARACTERISTICS
DC Leakage current does increase with tempera-
ture. The limits for 85ºC @ Rated Voltage and
105ºC @ 0.8 x Rated Voltage are both 10 times
the 25ºC limit.
7. Surge Current Capability
Certain applications may induce heavy surge cur-
rents when circuit impedance is very low (<0.1
ohm per volt). Driving inductance may also cause
voltage ringing. Surge currents may appear as
transients during turn-on of equipment.
The KO-CAP has a very high tolerance for surge
current. And although the failure mechanism is a
short circuit, they do not explode as may occur
with standard tantalums in such applications.
The KO-CAP series receives 100% screening for
surge current in our production process.
Capacitors are surged 4 times at full rated voltage
applied through a total circuit resistance of <0.5
ohms. Failures are removed during subsequent
electrical testing.
8. Dissipation Factor (DF)
Refer to part number tables for maximum DF
limits.
Dissipation factor is measured at 120 Hz, up to 1.0
volt rms maximum, and up to 2.5 volts DC maxi-
mum at +25ºC. The application of DC bias causes
a small reduction in DF, about 0.2% when full
rated voltage is applied. DF increases with
increasing frequency.
Dissipation factor is the ratio of the equivalent
series resistance (ESR) to the capacitive reac-
tance, (XC) and is usually expressed as a percent-
age. It is directly proportional to both capacitance
and frequency. Dissipation factor loses its impor-
tance at higher frequencies, (above about 1 kHz),
where impedance (Z) and equivalent series resis-
tance (ESR) are the normal parameters of concern.

XCR= Equivalent Series
Resistance (Ohms)
XC= Capacitive Reactance
(Ohms)
f= Frequency (Hertz)
C= Series Capacitance
(Farads)
DF is also referred to as tan or “loss tangent.”
The “Quality Factor,” “Q,” is the reciprocal of DF.
9. Equivalent Series Resistance (ESR) and
Impedance (Z)
The Equivalent Series Resistance (ESR) of the KO-
CAP is much lower than standard Tantalum caps
because the polymer cathode has much higher
conductivity. ESR is not a pure resistance, and it
decreases with increasing frequency.
Total impedance of the capacitor is the vector
sum of capacitive reactance (XC) and ESR, below
resonance; above resonance total impedance is
the vector sum of inductive reactance (XL) and
ESR.

10. AC Power Dissipation
Power dissipation is a function of capacitor size
and materials. Maximum power ratings have been
established for all case sizes to prevent overheat-
ing. In actual use, the capacitor’s ability to dissi-
pate the heat generated at any given power level
may be affected by a variety of circuit factors.
These include board density, pad size, heat sinks
and air circulation.

11. AC Operation
Permissible AC ripple voltage and current are
related to equivalent series resistance (ESR) and
power dissipation capability.
Permissible AC ripple voltage which may be
applied is limited by three criteria:
a. The positive peak AC voltage plus the DC bias
voltage, if any, must not exceed the DC voltage
rating of the capacitor.
b. The negative peak AC voltage, in combination
with bias voltage, if any, must not exceed the
permissible reverse voltage ratings presented
in Section 5.
c. The power dissipated in the ESR of the capaci-
tor must not exceed the appropriate value
specified in Section 10.
COMPONENT PERFORMANCE CHARACTERISTICS
A capacitor is a complex impedance consisting
of many series and parallel elements, each
adding to the complexity of the measurement
system.
L — Represents lead wire and construction
inductance. In most instances (especially in
solid tantalum and monolithic ceramic capaci-
tors) it is insignificant at the basic measurement
frequencies of 120 and 1000 Hz.
RS— Represents the actual ohmic series resis-
tance in series with the capacitance. Lead wires
and capacitor electrodes are contributing
sources.
RL— Capacitor Leakage Resistance. Typically it
can reach 50,000 megohms in a tantalum
capacitor. It can exceed 1012 ohms in monolithic
ceramics and in film capacitors.
Rd— The dielectric loss contributed by dielectric
absorption and molecular polarization. It
becomes very significant in high frequency mea-
surements and applications. Its value varies with
frequency.
Cd— The inherent dielectric absorption of the
solid tantalum capacitor which typically equates
to 1-2% of the applied voltage.
As frequency increases, XCcontinues to
decrease according to its equation above. There
is unavoidable inductance as well as resistance
in all capacitors, and at some point in frequency,
the reactance ceases to be capacitive and
becomes inductive. This frequency is called the
self-resonant point. In solid tantalum capacitors,
the resonance is damped by the ESR, and a
smooth, rather than abrupt, transition from
capacitive to inductive reactance follows.
Figure 4 compares the frequency response of a
KO-CAP to a standard Tantalum chip. See also
frequency curves shown in the T520 section,
p.39. Maximum limits for 100 kHz ESR are listed
in the part number tables for each series.

20. Failure Mechanism and Reliability
The normal failure mechanism is dielectric break-
down. Dielectric failure can result in high DC
Leakage current and may proceed to the level of a
short circuit. With sufficient time to charge, heal-
ing may occur by one of two potential mecha-
nisms. The polymer adjacent to the dielectric fault
site may overheat and vaporize, disconnecting the
fault site from the circuit. The polymer may also
Actual power dissipated may be calculated from
the following:
P =I2R
Substituting I = E, P = E2R
Z Z2
where:
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
P = power (watts)
Z = impedance at specified frequency (ohms)
R = equivalent series resistance at specified
frequency (ohms)
Using P max from Table 3, maximum allowable
rms
ripple current or voltage may be determined as
follows:
I(max) = P max/RE(max) = Z P max/R
These values should be derated at elevated tem-
peratures as follows:

Failure rates may be improved in application by
derating the voltage applied to the capacitor.
KEMET recommends that KO-CAPs be derated
to 80% or less of the rated voltage in application.
KO-CAPs exhibit a benign failure mode in that
they do not fail catastophically even under typical
fault conditions. If a shorted capacitor is allowed
to pass unlimited current, it may overheat and the
case may discolor. But this is distinctly different
from the explosive “ignition” that may occur with
standard MnO2 cathode tantalums. Replacement
of the MnO2 by the polymer removes the oxygen
that fuels ignition during a failure event.

oxidize into a more resistive material that plugs
the defect site in the dielectric and reduces the
flow of current.
Capacitor failure may be induced by exceeding
the rated conditions of forward DC voltage,
reverse DC voltage, surge current, power dissipa-
tion or temperature. Excessive environmental
stress, such as prolonged or high temperature
reflow processes may also trigger dielectric failure.

high integrity solder fillets. Preheating of these
components is recommended to avoid extreme
thermal stress. The maximum recommended
preheat rate is 2ºC per second.
Hand-soldering should be avoided. If necessary,
it should be performed with care due to the diffi-
culty in process control. Care should be taken to
avoid contact of the soldering iron to the molded
case. The iron should be used to heat the solder
pad, applying solder between the pad and the
termination, until reflow occurs. The iron should
be removed. “Wiping” the edges of a chip and
heating the top surface is not recommended.
During typical reflow operations a slight darken-
ing of the gold-colored epoxy may be observed.
This slight darkening is normal and is not harmful
to the product. Marking permanency is not affect-
ed by this change.
33. Washing
Standard washing techniques and solvents are
compatible with all KEMET surface mount tanta-
lum capacitors. Solvents such as Freon TMC and
TMS, Trichlorethane, methylene chloride, prelete,
and isopropyl alcohol are not harmful to these
components. Please note that we are not endors-
ing the use of banned or restricted solvents. We
are simply stating that they would not be harmful
to the components.
If ultrasonic agitation is utilized in the cleaning
process, care should be taken to minimize energy
levels and exposure times to avoid damage to the
terminations.
KEMET tantalum chips are also compatible with
newer aqueous and semi-aqueous processes.
34. Encapsulations
Under normal circumstances, potting or encapsu-
lation of KEMET tantalum chips is not required.
35. Storage Environment
Tantalum chip capacitors should be stored in nor-
mal working environments. While the chips them-
selves are quite robust in other environments,
solderability will be degraded by exposure to high
temperatures, high humidity, corrosive atmos-
pheres, and long term storage. In addition, pack-
aging materials will be degraded by high temper-
ature - reels may soften or warp, and tape peel
force may increase. KEMET recommends that
maximum storage temperature not exceed 40
degrees C, and the maximum storage humidity
not exceed 60% relative humidity. In addition,
temperature fluctuations should be minimized to
avoid condensation on the parts, and atmos-
pheres should be free of chlorine and sulfur bear-
ing compounds. For optimized solderability, chip
stock should be used promptly, preferably within
1.5 years of receipt.
30. Termination Coating
The standard finish coating is 90/10 Sn/Pb solder
(Tin/Lead-solder coated). 100% tin coating is
available upon request.
31. Recommended Mounting Pad Geometries
Proper mounting pad geometries are essential for
successful solder connections. These dimensions
are highly process sensitive and should be
designed to maximize the intergrity of the solder
joint, and to minimize component rework due to
unacceptable solder joints.
Figure 5 illustrates pad geometry. The table pro-
vides recommended pad dimensions for reflow
soldering techniques. These dimensions are
intended to be a starting point for circuit board
designers, to be fine tuned, if necessary, based
upon the peculiarities of the soldering process
and/or circuit board design.

29. Handling
Automatic handling of encapsulated components
is enhanced by the molded case which provides
compatibility with all types of high speed pick and
place equipment. Manual handling of these
devices presents no unique problems. Care
should be taken with your fingers, however, to
avoid touching the solder-coated terminations as
body oils, acids and salts will degrade the sol-
derability of these terminations. Finger cots
should be used whenever manually handling all
solderable surfaces.
