Reminders for Using These Products:

• Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
• Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
• Handling: Avoid direct contact with terminals due to hand oils; handle carefully to prevent damage.
• Bending: Do not excessively bend terminals to prevent wire fracture.
• Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
• Magnetic Fields: Keep away from magnets or magnetic objects.
• Soldering: Preheat before soldering; temperature difference between solder and chip should not exceed 150C. Post-mounting soldering corrections must be within specifications to avoid damage.
• Thermal Design: Account for self-heating when power is applied.
• Layout: For non-magnetic shielded types, careful coil placement on the PCB is advised to prevent malfunction due to magnetic interference.
