Reminders for Using These Products
- Storage: Within 12 months, under conditions (5~40C, 35-65% RH or less). Soldering of terminal electrodes may deteriorate if storage period elapses.
- Environment: Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that may inhibit soldering. Handle products carefully to prevent damage from dropping or inappropriate removal.
- Terminal Bending: Do not bend terminals with excessive stress to prevent wire fracture.
- Cleaning: Do not rinse coils. Contact SXN if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Be sure to 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 specification limits. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow sufficient margin for thermal design, as self-heating occurs when power is ON.
- Non-Magnetic Shield Type: Carefully lay out the coil on the circuit board to prevent malfunctions due to magnetic interference.
