Product Packaging

Reminders for Using These Products

• Storage: Within 12 months, at 5~40C and 35-65% RH.
• Environment: Avoid gas corrosive environments (salt, acid, alkali).
• Handling: Avoid touching electrodes with bare hands. Handle carefully to prevent damage.
• Terminal Bending: Do not bend terminals with excessive stress.
• Cleaning: Do not rinse coils; contact manufacturer if cleaning is necessary.
• Magnetic Fields: 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 performance degradation.
• Self-Heating: Account for self-heating in thermal design.
• Layout: For non-magnetic shield types, careful PCB layout is needed to prevent malfunction due to magnetic interference.
