I Cautions and Warnings:

The following conditions apply to all goods within the product series of WE-TFC

of Würth Elektronik eiSos GmbH & Co. KG:

General:

All recommendations according to the general technical specifications of the data sheet have to be complied with.

The usage and operation of the product within ambient conditions, which probably alloy or harm the wire isolation, has to be avoided.

If the product is potted in customer applications, the potting material might shrink during and after hardening. The product is exposed to the

pressure of the potting material with the effect that the core, wire and termination is possibly damaged by this pressure and so the electrical

as well as the mechanical characteristics are endangered to be affected. After the potting material is cured, the core, wire and termination of

the product have to be checked if any reduced electrical or mechanical functions or destructions have occurred.

The responsibility for the applicability of customer specific products and use in a particular customer design is always within the authority of

the customer. All technical specifications for standard products do also apply to customer specific products.

Cleaning agents that are used to clean the customer application might damage or change the characteristics of the component, body, pins or

termination.

Direct mechanical impact to the product shall be prevented as the ferrite material of the core could flake or in the worst case it could break.

Product specific:

Follow all instructions mentioned in the data sheet, especially:

?The soldering profile has to be complied with according to the technical wave soldering specification, otherwise this will void the warranty.

?Reflow soldering is only allowed after evaluation and approval.

?All products shall be used before the end of the period of 12 months based on the product date code, if not a 100% solderability can′t be

guaranteed.

?Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.

?Due to heavy weight of the component, strong forces and high accelerations might have the effect to damage the electrical connection or

to harm the circuit board and will void the warranty.
