Reminders for Using These Products
- Storage period is within 12 months under conditions (5~40C, 35-65% RH).
- Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Do not touch electrodes directly with bare hands to prevent soldering issues.
- Handle products carefully to prevent damage from dropping or mishandling.
- Do not bend terminals excessively to avoid 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; ensure temperature difference between solder and chip is within 150C.
- Soldering corrections after mounting should be within specified conditions to avoid damage.
- Allow sufficient thermal design margin for self-heating when power is ON.
- For non-magnetic shield types, carefully consider coil placement in PCB design to prevent malfunctions due to magnetic interference.
