Notes:
Effective January 2014, only for EMI supression capacitors:
– UL 60384-14 certification replaces both UL 1414 and UL 1283 standards.
– CSA C22.2 No. 1 and CSA C22.s No. 8 are replaced by CSA E60384-14.
– References like 1414, 1283 are removed from the capacitor marking
Capacitors under UL1414, UL1283 produced during or before 2013, are
accepted under UL scope.
Capacitors under CSA C22.2 No.1 / No. 8 produced during or before 2013,
are accepted under cUL scope.

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.

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 recommends the following conditions:
Pre-heating with a maximum temperature of 110 °C
Temperature inside the capacitor should not exceed the following limits:
ꢀ MKP/MFP 110 °C
ꢀ MKT 160 °C
When SMD components are used together with leaded ones, the leaded film capacitors should
not pass into the SMD adhesive curing oven. The leaded components should be assembled af-
ter the SMD curing step.
Leaded film capacitors are not suitable for reflow soldering.
Uncoated capacitors
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

Design of EMI Capacitors
EPCOS EMI capacitors use polypropylene (PP) film metalized with a thin layer of Zinc (Zn).
The following key points have made this design suitable to IEC/UL testing, holding a minimum
size.
Overvoltage AC capability with very high temperature Endurance test of IEC60384-14
(3rd edition, 2005-07) / UL60384-14 (1st edition, 2009-04) must be performed at 1.25 × VR at
maximum temperature, during 1000 hours, with a capacitance drift less than 10%.
Higher breakdown voltage withstanding if compared to other film metallizations, like Aluminum.
IEC60384-14 (3rd edition, 2005-07) / UL60384-14 (1st edition, 2009-04) establishes high
voltage tests performed at 4.3 × VR ꢀ1 minute, impulse testing at 2500 V for C= 1 µF and active
flammability tests.
Damp heat steady state: 40 °C/ 93% RH / 56 days. (without voltage or current load)
Effect of humidity on capacitance stability
Long contact of a film capacitor with humidity can produce irreversible effects. Direct contact with
liquid water or excess exposure to high ambient humidity or dew will eventually remove the film
metallization and thus destroy the capacitor. Plastic boxed capacitors must be properly tested in
the final application at the worst expected conditions of temperature and humidity in order to
check if any parameter drift may provoke a circuit malfunction.
In case of penetration of humidity through the film, the layer of Zinc can be degraded, specially
under AC operation (change of polarity), accelerated by the temperature, provoking an increment
of the serial resistance of the electrode and eventually a reduction of the capacitance value.
For DC operation, the parameter drift is much less.
Plastic boxes and resins can not protect 100% against humidity. Metal enclosures, resin potting or
coatings or similar measures by customers in their applications will offer additional protection
against humidity penetration.

Important notes
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).
