Important notes

he 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. Conse-

quently, 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).
