Cautions and warnings

■ Please note the recommendations in our Inductors data book (latest edition) and in the data

sheets.

– Particular attention should be paid to the derating curves given there.

– The soldering conditions should also be observed. Temperatures quoted in relation to wave

soldering refer to the pin, not the housing.

■ If the components are to be washed varnished it is necessary to check whether the washing

varnish agent that is used has a negative effect on the wire insulation, any plastics that are used,

or on glued joints. In particular, it is possible for washing varnish agent residues to have a

negative effect in the long-term on wire insulation

Washing processes may damage the product due to the possible static or cyclic mechanical

loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts,

which might lead to reduced reliability or lifetime.

■ The following points must be observed if the components are potted in customer applications:

– Many potting materials shrink as they harden. They therefore exert a pressure on the plastic

housing or core. This pressure can have a deleterious effect on electrical properties, and in

extreme cases can damage the core or plastic housing mechanically.

– It is necessary to check whether the potting material used attacks or destroys the wire

insulation, plastics or glue.

– The effect of the potting material can change the high-frequency behaviour of the components.

■ Ferrites are sensitive to direct impact. This can cause the core material to flake, or lead to

breakage of the core.

■ Even for customer-specific products, conclusive validation of the component in the circuit can

only be carried out by the customer.

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

requirements 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 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 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 life-saving 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 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. 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

foregoing for customer-specific products.

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, BAOKE, Alu-X, CeraDiode, CeraLink, CSMP, CSSP, CTVS, DeltaCap,
