Reminders for Using These Products
- Storage: Within 12 months, under 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals to maintain solderability. Handle carefully to prevent damage.
- Bending: Do not excessively bend terminals.
- Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Ensure preheating before soldering, with a temperature difference not exceeding 150C between solder and chip.
- Soldering Corrections: Perform within specified conditions to avoid performance degradation.
- Thermal Design: Account for self-heating when powered on.
- Layout: For non-magnetic shielded types, careful coil placement is needed to avoid malfunction due to magnetic interference.
