Reminders for Using These Products:
- Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands to prevent solderability issues.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals excessively 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; ensure temperature difference between solder and chip is within 150C.
- Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
- Allow for sufficient thermal design margin due to self-heating when power is on.
- For non-magnetic shielded types, carefully consider coil layout on the PCB to prevent malfunctions due to magnetic interference.
