Reminders for Using These Products
- Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Avoid touching electrodes directly with bare hands due to oil secretions.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Do not expose products to 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 short circuits, performance deterioration, or lifespan shortening.
- Allow for sufficient thermal design margin as products self-heat during operation.
- For non-magnetic shield types, carefully lay out the coil on the circuit board to prevent malfunctions due to magnetic interference.
