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 to maintain solderability; handle with care to prevent damage.
- Soldering: Preheat components before soldering; ensure temperature difference does not exceed 150C. Post-mounting soldering corrections should adhere to specifications to avoid performance degradation.
- Thermal Design: Account for self-heating when the device is powered on.
- Magnetic Fields: Keep away from magnets or magnetic objects.
