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 due to hand grease. Handle carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
- 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 within specified conditions; overheating may cause issues.
- Self-Heating: Account for self-heating when designing for thermal management.
- Non-Magnetic Shielded Type: Careful layout is required to prevent malfunction due to magnetic interference.
