8 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 reer to the pin, not the housing. I the components are to be washed varnished it is necessary to check whether the washing varnish agent that is used has a negative eect on the wire insulation, any plastics that are used, or on glued joints. In particular, it is possible or washing varnish agent residues to have a negative eect in the long-term on wire insulation. The ollowing points must be observed i the components are potted in customer applications: Many potting materials shrink as they harden. They thereore exert a pressure on the plastic housing or core. This pressure can have a deleterious eect 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 eect o the potting material can change the high-requency behaviour o the components. Ferrites are sensitive to direct impact. This can cause the core material to lake, or lead to breakage o the core. Even or customer-speciic products, conclusive validation o the component in the circuit can only be carried out by the customer. 8 /8

9 Important notes The ollowing applies to all products named in this publication: 1. Some parts o this publication contain statements about the suitability o our products or certain areas o application. These statements are based on our knowledge o typical requirements that are oten placed on our products in the areas o application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability o our products or a particular customer application. As a rule, EPCOS is either unamiliar with individual customer applications or less amiliar 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 speciication is suitable or use in a particular customer application. 2. We also point out that in individual cases, a malunction o electronic components or ailure beore the end o their usual service lie cannot be completely ruled out in the current state o the art, even i they are operated as speciied. In customer applications requiring a very high level o operational saety and especially in customer applications in which the malunction or ailure o an electronic component could endanger human lie or health (e.g. in accident prevention or lie-saving systems), it must thereore be ensured by means o suitable design o the customer application or other action taken by the customer (e.g. installation o protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event o malunction or ailure o an electronic component. 3. The warnings, cautions and product-speciic notes must be observed.. In order to satisy certain technical requirements, some o the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useul inormation on this will be ound in our Material Data Sheets on the Internet ( Should you have any more detailed questions, please contact our sales oices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change rom time to time. The same is true o the corresponding product speciications. Please check thereore to what extent product descriptions and speciications contained in this publication are still applicable beore or when you place an order. We also reserve the right to discontinue production and delivery o products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aorementioned does not apply in the case o individual agreements deviating rom the oregoing or customer-speciic products. 6. Unless otherwise agreed in individual contracts, all orders are subject to the current version o the General Terms o Delivery or Products and Services in the Electrical Industry published by the German Electrical and Electronics Industry Association (ZVEI). 7.
