Cautions and warnings

Personal safety

The electrolytes used by EPCOS have not only been optimized with a view to the intended

application, but also with regard to health and environmental compatibility. They do not contain

any solvents that are detrimental to health, e.g. dimethyl formamide (DMF) or dimethyl acetamide

(DMAC).

Furthermore, part of the high-voltage electrolytes used by EPCOS are self-extinguishing. They

contain flame-retarding substances which will quickly extinguish any flame that may have been

ignited.

As far as possible, EPCOS does not use any dangerous chemicals or compounds to produce

operating electrolytes. However, in exceptional cases, such materials must be used in order to

achieve specific physical and electrical properties because no safe substitute materials are

currently known. However, the amount of dangerous materials used in our products has been

limited to an absolute minimum. Nevertheless, the following rules should be observed when

handling aluminum electrolytic capacitors:

Any escaping electrolyte should not come into contact with eyes or skin.

If electrolyte does come into contact with the skin, wash the affected parts immediately with

running water. If the eyes are affected, rinse them for 10 minutes with plenty of water. If

symptoms persist, seek medical treatment.

Avoid breathing in electrolyte vapor or mists. Workplaces and other affected areas should be

well ventilated. Clothing that has been contaminated by electrolyte must be changed and

rinsed in water.

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).
