- Environment: Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals with bare hands. Handle products carefully to prevent damage.
- Terminal Bending: Do not bend terminals with excessive stress.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. Temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform after mounting within specified conditions. Overheating may cause issues.
- Thermal Design: Allow sufficient margin for self-heating when power is on.
- Non-magnetic Shield Type: Careful layout is required on the PCB to prevent malfunction due to magnetic interference.
