Reminders for Using These Products
- Storage: Within 12 months, at 5~40C and 35~65% RH. 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 affecting solderability. Handle carefully to prevent damage from dropping.
- 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.
- Magnetism: 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. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is ON; ensure sufficient thermal design margin.
- Non-magnetic Shielded Type: Careful coil layout on the PCB is required to prevent malfunctions due to magnetic interference.
