Cautions and warnings
Current-compensated ring core double chokes
■ 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. Derating must be applied
in case the ambient temperature in the application exceeds the rated temperature of the
component.
– Ensure the operation temperature (which is the sum of the ambient temperature and the
temperature rise caused by losses / self-heating) of the component in the application does not
exceed the maximum value specified in the climatic category.
– 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.

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 (www.tdk-electronics.tdk.com/material). Should you have any more detailed 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 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.
