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: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that can inhibit soldering. Handle products carefully to prevent damage from dropping or improper removal.
- Terminal Bending: Do not bend terminals with excessive stress 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: Always preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
- Soldering Correction: Soldering corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Self-Heating: Account for self-heating when power is applied; ensure sufficient thermal design margin.
- Non-Magnetic Shield Type: Carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
