Reminders for Using These Products
- Storage period within 12 months; conditions: 5~40C, 35~65% RH.
- Avoid use and storage in corrosive environments (salt, acid, alkali).
- Do not touch electrodes directly with bare hands to maintain solderability.
- Handle carefully to prevent damage from dropping or improper removal.
- Do not bend terminals excessively to avoid wire fracture.
- 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 short circuits, performance degradation, or lifespan reduction.
- Allow sufficient thermal design margin for self-heating during operation.
