Product Packaging

Reminders for Using These Products

• Storage: Storage period is within 12 months. Conditions: temperature 5~40C, humidity 35~65% RH or less. Terminal electrode solderability may deteriorate if the storage period elapses.
• Environment: Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
• Handling: Avoid touching electrodes directly with bare hands. Handle products carefully to prevent damage from dropping or improper removal. Do not bend terminals with excessive stress.
• Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
• Magnetic Fields: Do not expose products to magnets or strong magnetic fields.
• Soldering: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C. Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
• Thermal Design: Self-heating occurs when power is on; ensure sufficient thermal design margin.
• Layout: For non-magnetic shield types, careful coil placement on the circuit board is required to prevent malfunctions due to magnetic interference.
