Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils. Handle carefully to prevent damage.
- Terminals: Do not bend terminals excessively.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Ensure preheating before soldering to keep temperature difference within 150C.
- Soldering Corrections: Perform within specification limits to avoid performance degradation.
- Self-heating: Account for self-heating in thermal design.
- Layout: For non-shielded types, consider coil placement to avoid malfunction due to magnetic interference.
