Reminders for Using These Products:
- Storage period is within 12 months under conditions (temperature: 5~40C, humidity: 35 to 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 soldering issues.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; ensure temperature difference between solder and chip is within 150C.
- Soldering corrections after mounting should adhere to specified conditions to avoid performance degradation.
- Account for self-heating when power is applied in thermal design.
- Careful coil placement is required for non-magnetic shield types to prevent malfunctions due to magnetic interference.
