I Cautions and Warnings:
The following conditions apply to all goods within the product series of WE-PBF
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 disposal and operation of the product within ambient conditions which probably alloy or harm the component surface has to be avoided.
If the product is potted in customer applications, the potting material might shrink during and after hardening. Accordingly to this the product
is exposed to the pressure of the potting material with the effect that the ferrite body and termination is possibly damaged by this pressure and
so the electrical as well as the mechanical characteristics are endanger to be affected. After the potting material is cured, the ferrite body 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 for customer specific products.
Washing varnish agent that is used during the production to clean the application might damage or change the characteristics of the plating.
The washing varnish agent could have a negative effect on the long term function of the product.
Direct mechanical impact to the product shall be prevented as the ferrite material of the ferrite body could flake or in the worst case it could
break.
Product specific:
Follow all instructions mentioned in the datasheet, especially:
•The solder profile has to be complied with according to the technical reflow soldering specification, otherwise no warranty will be sustai-
ned.
• Wave soldering is only allowed after evaluation and approval.
•All products are supposed to be used before the end of the period of 12 months based on the product date-code, if not a 100% solderabi-
lity can´t be warranted.
•Violation of the technical product specifications such as exceeding the nominal rated current will result in the loss of warranty.
