Reminders for Using These Products

• Storage: Within 12 months, at 5~40C and 35~65% RH.
• Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
• Handling: Avoid direct contact with terminals to maintain solderability. Handle carefully to prevent damage.
• Bending: Do not excessively bend terminals.
• Cleaning: Do not rinse coils; contact SXN if cleaning is necessary.
• Magnetism: Keep away from magnets or magnetic fields.
• Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
• Soldering Corrections: Perform within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
• Thermal Design: Account for self-heating when power is on.
• Layout: For non-magnetic shielded types, careful coil placement on the PCB is required to prevent malfunction due to magnetic interference.
