Precautions for Use
To avoid failure, especially short circuit mode, under severe electrical or mechanical stress beyond specified ratings and conditions, adhere to the following:
- Soldering Profile: Follow recommended temperature profiles to prevent cracks due to sudden temperature changes.
- Manual Soldering: Handle soldering irons carefully to avoid direct contact with the ceramic body and select appropriate tips and temperatures.
- Optimum Solder Amount: Use recommended solder amounts for reflow and wave soldering.
Contact engineering or factory for handling precautions and application notes.
