Reminders for Using These Products
- Storage period within 12 months under 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.
- Handle carefully to prevent damage.
- Do not excessively bend terminals.
- Do not rinse coils; contact manufacturer if cleaning is required.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; temperature difference should not exceed 150C.
- Soldering corrections after mounting should be within specifications to avoid performance issues.
- Consider self-heating in thermal design.
- For non-magnetic shielded types, careful PCB layout is needed to prevent magnetic interference.
