- Rated DC Current: The lesser value of Isat or Irms.
Reminders for Using These Products
- Storage period is within 12 months under conditions (5~40C, 35-65% RH).
- Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Do not touch terminals directly with bare hands to prevent soldering issues.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- Do not rinse coils; contact 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 reduced lifespan.
- Allow sufficient thermal design margin for self-heating during operation.
- For non-magnetic shield types, careful layout is required to prevent malfunction due to magnetic interference.
