Reminders for Using These Products:
- Storage period: within 12 months. Storage 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 to prevent reduced solderability due to hand oils.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not excessively bend terminals to avoid wire fracture.
- Do not rinse coils; contact the manufacturer if cleaning is required.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; ensure the temperature difference between solder and chip does not exceed 150C.
- Soldering corrections after mounting should be within specified conditions to avoid overheating, short circuits, performance degradation, or lifespan reduction.
- Account for self-heating when the product is powered on in thermal design.
- For non-magnetic shield types, carefully consider coil placement on the PCB to prevent malfunctions due to magnetic interference.
