Reminders for Using These Products
- Storage: Store within 12 months under conditions of 5~40C and 35-65% RH. Terminal solderability may deteriorate if storage period is exceeded.
- Environment: Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
- Handling: Avoid touching terminals directly with bare hands due to oil secretions that can inhibit soldering. Handle products carefully to prevent damage from dropping or improper removal. Do not bend terminals excessively.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is required.
- Magnetic Fields: Keep away from magnets or objects with magnetic fields.
- Soldering: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C. Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Self-heating occurs when power is on; ensure sufficient allowance in thermal design.
- Layout: For non-magnetic shield types, careful coil placement is necessary to prevent malfunctions due to magnetic interference.
