Usage Precautions
- Storage period: within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Avoid use and storage in corrosive environments (salt, acid, alkali, etc.).
- Do not touch terminals directly with bare hands to prevent solderability issues.
- Handle products 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 products away from magnets or magnetic fields.
- Preheat components before soldering; the temperature difference between solder and chip should not exceed 150C.
- Soldering corrections after mounting should adhere to specified conditions to prevent short circuits, performance degradation, or reduced lifespan.
- Allow for sufficient thermal design due to self-heating when power is applied.
- For non-magnetic shielded types, careful coil layout is required to prevent malfunctions due to magnetic interference.
