Usage Precautions

• Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
• Avoid use and storage in corrosive environments (salt, acid, alkali).
• Do not touch terminals directly with bare hands.
• Handle with care to prevent damage from dropping.
• Avoid excessive bending of terminals.
• Do not rinse coils; contact the manufacturer if cleaning is necessary.
• Keep away from magnets or magnetic fields.
• Preheat components before soldering; ensure temperature difference between solder and chip does not exceed 150C.
• Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
• Allow for sufficient thermal design margin due to self-heating when powered on.
• For non-magnetic shield types, careful coil placement on the PCB is required to prevent malfunctions due to magnetic interference.
