Reminders for Using These Products:
- Storage: Within 12 months, at 5~40C and 65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils. Handle carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is required.
- Magnetic Fields: Do not expose to magnets or magnetic fields.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform after mounting within specified conditions; overheating can cause issues.
- Thermal Design: Allow for self-heating when power is on.
- Layout: For non-magnetic shield types, carefully consider coil placement to avoid malfunction due to magnetic interference.
