Reminders for Using These Products:
- Storage: Within 12 months, temperature: 5~40C, humidity: 35~65% RH or less.
- Avoid use or storage in gas corrosive environments (salt, acid, alkali, etc.).
- Do not touch electrodes directly with bare hands to prevent soldering issues.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils; contact SXN 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 overheating.
- Allow sufficient thermal design margin for self-heating when power is on.
- For non-magnetic shield types, careful coil layout is needed to prevent malfunctions due to magnetic interference.
