Reminders for Using These Products
- Storage period is within 12 months under conditions of 5~40C and 35~65% RH.
- Avoid use and storage in corrosive environments (salt, acid, alkali, etc.).
- Do not touch electrodes 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 performance degradation.
- Ensure sufficient thermal design margin for self-heating when power is on.
- For non-magnetic shield types, careful PCB layout is required to prevent malfunction due to magnetic interference.
