Mounting information

When bending the leads, take care that the bending

point is at least 3 mm apart from the face ends of the

core and that the start-of-winding-areas are not subject-

ed to any mechanical stress.

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 require-

ments that are often placed on our products in the areas of application concerned. We neverthe-

less 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 incumbent on the

customer to check and decide whether an EPCOS product with the properties described 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 passive 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 re-

quiring a very high level of operational safety and especially in customer applications in which the

malfunction or failure of a passive electronic component could endanger human life or health

(e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of suit-

able 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 a passive 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 pub-

lication may contain substances subject to restrictions in certain jurisdictions (e.g. be-

cause they are classed as “hazardous”). Useful information on this will be found in our Material

Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed

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. Consequent-

ly, we cannot guarantee that all products named in this publication will always be available.

6. Unless otherwise agreed in individual contracts, all orders are subject to the current version

of the “General Terms of Delivery for Products and Services in the Electrical Industry”

published by the German Electrical and Electronics Industry Association (ZVEI).

7. The trade names EPCOS, CeraDiode, CSSP, PhaseCap, PhaseMod, SilverCap, SIFI, SIMID,

SIKOREL, SIOV, SIP5D, SIP5K, TOPcap, UltraCap, WindCap are trademarks registered or

pending in Europe and in other countries. Further information will be found on the Internet at
