Reminders for Using These Products
- 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 grease. Handle with care to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is required.
- 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 to avoid performance degradation.
- Thermal Design: Account for self-heating when power is ON.
- Non-Magnetic Shield Type: Careful PCB layout is required to prevent malfunction due to magnetic interference.
