Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Solderability may deteriorate if storage period elapses.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Do not touch electrodes directly with 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 avoid wire fracture.
- Cleaning: Do not rinse coils without contacting the manufacturer.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections must be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is applied; ensure sufficient thermal design margin.
- Layout: For non-magnetic shielded types, careful coil layout on the circuit board is necessary to prevent malfunctions due to magnetic interference.
