RoHS compatible
RoHS-compatible means that products are compatible with the
requirements according to Art. 4 (substance restrictions) of
Directive 2011/65/EU of the European Parliament and of the
Council of June 8th, 2011, on the restriction of the use of certain
hazardous substances in electrical and electronic equipment
("Directive") with due regard to the application of exemptions as
per Annex III of the Directive in certain cases.

Important notes
The following applies to all products named in this publication:

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.
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.
The warnings, cautions and product-specific notes must be observed.
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.
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.
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).
