Usage Reminders
- Storage Period: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oil affecting solderability. Handle carefully to prevent damage. Do not bend terminals excessively.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose to magnets or magnetic fields.
- Soldering: Preheat components before soldering; ensure temperature difference between solder and chip does not exceed 150C. Post-mounting soldering corrections should be within specified conditions.
- Thermal Design: Account for self-heating when the power is ON.
