Reminders for Using These Products

Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
Environment: Avoid gas corrosive environments (salt, acid, alkali, etc.).
Handling: Avoid direct contact with terminals due to hand grease. Handle carefully to prevent damage. Do not bend terminals excessively.
Cleaning: Do not rinse coils; contact the manufacturer if cleaning is necessary.
Magnetic Fields: Keep away from magnets or magnetic objects.
Soldering: Preheat components before soldering. Ensure temperature difference between solder and chip is within 150C.
Post-Mounting Correction: Perform within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
Thermal Design: Account for self-heating when power is on.
Non-Shielded Type Layout: Careful coil placement on the PCB is needed to prevent malfunctions due to magnetic interference.
