Reminders for Using These Products:
- Storage period within 12 months under conditions (5~40C, 35~65% RH).
- Avoid use and storage in corrosive environments.
- Handle with care to avoid damage; do not touch electrodes directly with bare hands.
- Avoid excessive bending of terminals.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering corrections should be within specifications to avoid performance degradation.
- Consider self-heating during operation for thermal design.
- For non-magnetic shield types, careful coil placement on the PCB is required to prevent malfunction due to magnetic interference.
