Reminders for Using These Products

Storage: Within 12 months, under 5~40C and 35~65% RH. 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 touching electrodes directly with bare hands due to oil secretions. Handle products carefully to prevent damage from dropping or improper removal. Do not bend terminals excessively.
Cleaning: Do not rinse coils. Contact SXN if cleaning is necessary.
Magnetic Fields: Do not expose products to magnets or magnetic fields.
Soldering: Preheat components before soldering; 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 lifespan reduction.
Thermal Design: Self-heating occurs when power is ON; ensure sufficient allowance in thermal design.
Layout: For non-magnetic shield types, careful coil layout is required to prevent malfunctions due to magnetic interference.
