Reminders for Using These Products:
- Storage period is within 12 months under conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions that may inhibit soldering.
- 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; 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 deterioration, or lifespan shortening.
- Consider self-heating when designing for thermal management.
- For non-magnetic shield types, careful layout is required to prevent malfunctions due to magnetic interference.
