Reminders for Using These Products:
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Terminal solderability may deteriorate beyond this period.
- Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that inhibit soldering. Handle products carefully to prevent damage from dropping or improper removal.
- Terminal Bending: Do not bend terminals excessively to prevent wire fracture.
- 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. The temperature difference between solder and chip temperature should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating (temperature increase) when power is ON. Ensure sufficient thermal design margin.
- Non-Magnetic Shield Type: Carefully consider coil placement in PCB design to prevent malfunctions due to magnetic interference.
