Note: Saturation Current (Isat): DC current at which inductance drops 10% from its value without current. Temperature Rise Current (Irms): the actual value of DC current when the temperature rise is T 40 (Ta=25). Rated DC Current is the lesser of Isat or Irms. Component temperature should be verified in the end application.

Recommended Reflow Soldering Curve:
The recommended reflow conditions are set according to our soldering equipment. Please adjust and confirm according to user's environment/equipment.
Reminders for Using These Products:
- Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35 to 65% RH or less.
- Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions.
- Handle products carefully to prevent damage from dropping or inappropriate removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils; contact the company if cleaning is necessary.
- Do not expose products to 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 lifespan reduction.
- Allow sufficient thermal design margin for self-heating when power is on.
- For non-magnetic shield types, carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
