Reminders for Using These Products:
- Storage period within 12 months under conditions (5~40C, 35~65% RH).
- Avoid use and storage in corrosive gas environments.
- Do not touch terminals directly with bare hands.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- 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 after mounting should be within specified conditions to avoid overheating.
- Allow sufficient thermal design margin for self-heating when power is ON.
- For non-magnetic shielded types, carefully lay out coils on the PCB to prevent magnetic interference.
