NOTE 1 An overvoltage equal to 1.5 VRfor 30 ms is permitted 1000 times during the life of the
capacitor.
The amplitudes of the overvoltages that may be tolerated without significant reduction in the life
time of the capacitor depend on their duration, the number of application and the capacitor
temperature.
In addition these values assume that the overvoltages may appear when the internal temperature
of the capacitor is less than 0 °C but within the temperature category.
NOTE 2 The average applied voltage must not be higher than the specified voltage.
Pulse handling capability
"dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal
voltages, expressed in V/μs.
Note:
The values of dV/dt provided below must not be exceeded in order to avoid damaging the
capacitor.

The equivalent heat coefficient "G (mW/ºC)" is given for measuring the temperature on the lateral
surface of the plastic box as figure1 shows. By using a thermocouple and avoiding effect of
radiation and convection the temperature measured during operation conditions should be a
result of the dissipated power divided by the equivalent heat coefficient.

Self Heating by power dissipation & equivalent heat coefficient
The IRMS and consequently the power dissipation must be limited during operation in order to not
exceed the maximum limit of ΔT allowed for this series. ΔTmax given for this series is equal or
lower than 20 °C at rated temperature (70 °C), for higher ambient temperatures ΔTmax (T) will have
the same derating factor than IRMS versus temperature and then an equivalent derating as per:
ambient temperatures ΔTmax (T) will have the same derating factor than IRMS versus temperature
and then an equivalent derating as per:
ΔTmax (T) = (Factor)2×ΔT (70 °C).
For any particular IRMS the ΔT may be calculated by:
ΔT(°C)=P
dis (mW) / G(mW/°C).
Where ΔT(°C) is the difference between the temperature measured on the box (see figure 1) and
the ambient temperature when capacitor is working during normal operation;
ΔT(°C)=T
op (°C) TA(°C).
It represents the increasing of temperature provoked by the IRMS during operation.
G (mW/°C) is the equivalent heat coefficient described above and Pdis (mW) is the dissipated
power defined by:
Pdis (mW) = ESRtyp (mΩ)×Irms2(ARMS).
Example for thermal calculation:
We will take as reference B32778G0306K (30 μF/1100 V) type for thermal calculation.
Considering the following load and capacitor characteristics:
IRMS :12A
RMS at 20 kHz TA:85°C30×45 ×57.5 box
G (mW/°C): 125
Then we have to find the ESRtyp at 20 kHz what is approx . 8.2 mΩ.
So according to:
Pdis (mW) = ESRtyp (mΩ)×Irms2(ARMS)
we have the following:
Pdis (mW) = 8.2 mΩ×12 ARMS2= 1181 mW
and as per:
ΔT(°C)=P
dis (mW) / G (mW/°C)
we have the following:
ΔT(°C) = 1181 (mW) / 125 (mW/°C) = 9.5 °C.
What is below of the
ΔTmax (85 °C) = (Factor)2×ΔT (70 °C) = (0.7)2×20 °C=9.8°C.
On the other hand we may confirm that max IRMS at 20 kHz at 70 °C = 17.5 ARMS
And then max IRMS for 85 °C of ambient temperature is defined as follows:
IRMS (85 °C) = Factor ×IRMS (70 °C) = 0.7 ×17.5 ARMS = 12.25 ARMS.
What confirms once again that IRMS (12 ARMS at 20 kHz) is below the max specified for such
frequency and ambient temperature.

1 Soldering
1.1 Solderability of leads
The solderability of terminal leads is tested to IEC 60068-2-20, test Ta, method 1.
Before a solderability test is carried out, terminals are subjected to accelerated ageing (to
IEC 60068-2-2, test Ba: 4 h exposure to dry heat at 155 °C). Since the ageing temperature is far
higher than the upper category temperature of the capacitors, the terminal wires should be cut off
from the capacitor before the ageing procedure to prevent the solderability being impaired by the
products of any capacitor decomposition that might occur.
Solder bath temperature 235 ±5°C
Soldering time 2.0 ±0.5 s
Immersion depth 2.0 +0/0.5 mm from capacitor body or seating plane

1.3 General notes on soldering
Permissible heat exposure loads on film capacitors are primarily characterized by the upper cate-
gory temperature Tmax. Long exposure to temperatures above this type-related temperature limit
can lead to changes in the plastic dielectric and thus change irreversibly a capacitor's electrical
characteristics. For short exposures (as in practical soldering processes) the heat load (and thus
the possible effects on a capacitor) will also depend on other factors like:
Pre-heating temperature and time
Forced cooling immediately after soldering
Terminal characteristics:
diameter, length, thermal resistance, special configurations (e.g. crimping)
Height of capacitor above solder bath
Shadowing by neighboring components
Additional heating due to heat dissipation by neighboring components
Use of solder-resist coatings
The overheating associated with some of these factors can usually be reduced by suitable coun-
termeasures. For example, if a pre-heating step cannot be avoided, an additional or reinforced
cooling process may possibly have to be included.
EPCOS recommendations
As a reference, the recommended wave soldering profile for our film capacitors is as follows:
B32774 ... B32778
MKP DC link high density series up to 480 μF
Page 40 of 48Please read Cautions and warnings and
Important notes at the end of this document.
Body temperature should follow the description below:
MKP capacitor
During pre-heating: Tp110 °C
During soldering: Ts120 °C, ts45 s
MKT capacitor
During pre-heating: Tp125 °C
During soldering: Ts160 °C, ts45 s
When SMD components are used together with leaded ones, the film capacitors should not pass
into the SMD adhesive curing oven. The leaded components should be assembled after the SMD
curing step.
Leaded film capacitors are not suitable for reflow soldering.
In order to ensure proper conditions for manual or selective soldering, the body temperature of
the capacitor (Ts) must be 120 °C.
One recommended condition for manual soldering is that the tip of the soldering iron should
be <360 °C and the soldering contact time should be no longer than 3 seconds.
For uncoated MKT capacitors with lead spacings 10 mm (B32560/B32561) the following mea-
sures are recommended:
pre-heating to not more than 110 °C in the preheater phase
rapid cooling after soldering

Cautions and warnings
Do not exceed the upper category temperature (UCT).
Do not apply any mechanical stress to the capacitor terminals.
Avoid any compressive, tensile or flexural stress.
Do not move the capacitor after it has been soldered to the PC board.
Do not pick up the PC board by the soldered capacitor.
Do not place the capacitor on a PC board whose PTH hole spacing differs from the specified
lead spacing.
Do not exceed the specified time or temperature limits during soldering.
Avoid external energy inputs, such as fire or electricity.
Avoid overload of the capacitors.
Consult us if application is with severe temperature and humidity condition.
There are no serviceable or repairable parts inside the capacitor. Opening the capacitor or
any attempts to open or repair the capacitor will void the warranty and liability of EPCOS.
Please note that the standards referred to in this publication may have been revised in the
meantime.

The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical re-
quirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incum-
bent on the customer to check and decide whether an EPCOS product with the properties de-
scribed in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or
failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in
which the malfunction or failure of an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by
means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Ma-
terial Data Sheets on the Internet (www.epcos.com/material). Should you have any more de-
tailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order. We also
reserve the right to discontinue production and delivery of products. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the fore-
going for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current ver-
sion of the "General Terms of Delivery for Products and Services in the Electrical In-
dustry" published by the German Electrical and Electronics Industry Association
(ZVEI).
