Usage Reminders

• Storage: Within 12 months, under 5~40C and 35~65% RH.
• Avoid use and storage in corrosive environments (salt, acid, alkali).
• Handle with care to avoid damage; do not touch terminals directly with bare hands.
• Avoid excessive bending of terminals.
• Do not clean coils; contact the manufacturer if cleaning is necessary.
• Keep away from magnets or magnetic fields.
• 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 damage or performance degradation.
• Account for self-heating during operation in thermal design.
• For non-magnetic shielded types, careful coil layout is needed to prevent malfunctions due to magnetic interference.
