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.

Display of ordering codes for EPCOS products

The ordering code for one and the same EPCOS product can be represented differently in data

sheets, data books, other publications, on the EPCOS website, or in order-related documents such as

shipping notes, order confirmations and product labels. The varying representations of the

ordering codes are due to different processes employed and do not affect the specifications of

the respective products. Detailed information can be found on the Internet under

www.epcos.com/orderingcodes
