Reminders for Using These Products
- Storage: Within 12 months, at 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to grease. Handle carefully to prevent damage. 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.
- Soldering: Preheat components before soldering. Ensure temperature difference between solder and chip is within 150C. Post-mounting corrections should adhere to specifications to avoid performance degradation.
- Thermal Design: Account for self-heating when power is on.
