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

1.3 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

information"

Storage conditions Make sure that capacitors are stored within the

specified range of time, temperature and humidity

conditions.

"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

Display of ordering codes for EPCOS products

The ordering code for one and the same product can be represented differently in data sheets,

data books, other publications and the website of EPCOS, or in order-related documents such as

shipping notes, order confirmations and product labels. The varying representations of the

ordering codes are due to different processes employed and do not affect the

specifications of the respective products. Detailed information can be found on the Internet

under www.epcos.com/orderingcodes.

Important notes at the end of this document.

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).
