Usage Precautions
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils. Handle with care 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; temperature difference between solder and chip should not exceed 150C. Soldering corrections after mounting should adhere to specified conditions to avoid performance degradation.
- Thermal Design: Account for self-heating when power is applied.
- Layout: For non-magnetic shield types, careful coil placement on the PCB is required to prevent malfunctions due to electromagnetic interference.
