Reminders for Using These Products
- Storage period: within 12 months. Conditions: temperature 5~40C, humidity 35~65% RH or less.
- Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Do not touch electrodes directly with bare hands to avoid reduced solderability.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to prevent wire fracture.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Keep products 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 short circuits, performance degradation, or reduced lifespan.
- Consider self-heating when designing for thermal management.
- For non-magnetic shield types, careful coil layout is needed to prevent malfunctions due to magnetic interference.
