Reminders for Using These Products
- Storage period within 12 months under conditions (5~40C, 35~65% RH).
- Avoid use and storage in gas 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 manufacturer if cleaning is necessary.
- Do not expose to 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 specifications.
- Allow sufficient thermal design margin for self-heating during operation.
- For non-magnetic shield types, careful coil layout is required to prevent malfunction due to magnetic interference.
