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.
■
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.

Important notes
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 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 we are 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 a 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
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 foregoing for customer-specific
products.
6. Unless
otherwise agreed in individual contracts,
all orders are subject to our General Terms and
Conditions of Supply.
7.
Our manufacturing sites serving the automotive business apply the IATF 16949 standard.
The IATF
certifications confirm our compliance with requirements regarding the quality management system in the
automotive industry. Referring to customer requirements and customer specific requirements (“CSR”) TDK
always has and will continue to have the policy of respecting individual agreements. Even if IATF 16949
may appear to support the acceptance of unilateral requirements, we hereby like to emphasize that
only
requirements mutually agreed upon can and will be implemented in our Quality Management
System.
For clarification purposes we like to point out that obligations from IATF 16949 shall only become
legally binding if individually agreed upon.
