Definitions:
- Saturation Current (Isat): DC current at which inductance drops 30% 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: The lesser value of Isat or Irms.

Recommended Reflow Soldering Curve:
The recommended reflow conditions are set according to the soldering equipment. Users should adjust and confirm conditions based on their specific environment and equipment.
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 environments with gas corrosion (salt, acid, alkali, etc.).
- Avoid direct contact with terminals by bare hands due to oil secretions affecting solderability.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils without authorization; contact the manufacturer if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering; the 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 reduced lifespan.
- Allow for sufficient thermal design margin due to self-heating when power is on.
- For non-magnetic shielded types, carefully lay out coils on the PCB to prevent malfunctions due to magnetic interference.
