Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid gas corrosive environments (salt, acid, alkali).
- Handling: Avoid direct contact with terminals due to hand oils. Handle carefully to prevent damage.
- Terminal Bending: Do not bend terminals excessively to prevent wire fracture.
- Cleaning: Do not clean coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Always preheat components before soldering; ensure temperature difference between solder and chip is within 150C.
- Soldering Corrections: Perform post-mounting soldering corrections within specified conditions to avoid overheating.
- Self-Heating: Account for self-heating when designing for thermal management.
- Layout: For non-magnetic shield types, carefully consider coil placement on the PCB to prevent malfunctions due to magnetic interference.
