Mounting guidelines
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
Evaluation criteria:
Visual inspection Wetting of wire surface by new solder ≥90%, free-flowing solder
1.2 Resistance to soldering heat
Resistance to soldering heat is tested to IEC 60068-2-20, test Tb, method 1A.

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 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

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.
The table below summarizes the safety instructions that must always be observed. A detailed de-
scription can be found in the relevant sections of the chapters "General technical information" and
"Mounting guidelines".
Topic Safety information Reference chapter
"General technical
information"
Storage conditions Make sure that capacitors are stored within the
specified range of time, temperature and humidity
conditions.
4.5
"Storage conditions"
Flammability Avoid external energy, such as fire or electricity
(passive flammability), avoid overload of the
capacitors (active flammability) and consider the
flammability of materials.
5.3
"Flammability"
Resistance to
vibration
Do not exceed the tested ability to withstand
vibration. The capacitors are tested to
IEC 60068-2-6.
EPCOS offers film capacitors specially designed
for operation under more severe vibration regimes
such as those found in automotive applications.

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).
