Reminders for Using These Products
- Storage: Within 12 months, under conditions (5~40C, 35~65% RH).
- Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils. Handle carefully to prevent damage.
- Soldering: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C. Post-mounting soldering corrections should be within specifications.
- Thermal Design: Account for self-heating when power is applied.
- Layout: For non-magnetic shield types, careful coil placement on the PCB is necessary to prevent malfunctions due to magnetic interference.
