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).
- Avoid direct contact with terminals due to hand oils affecting solderability.
- Handle carefully to prevent damage from dropping or improper removal.
- Do not excessively bend terminals.
- Do not rinse coils; contact SXN if cleaning is necessary.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; temperature difference should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions to avoid performance degradation.
- Consider self-heating (temperature increase) in thermal design.
- For non-magnetic shielded types, careful layout is required to prevent malfunction due to magnetic interference.
