Definitions:
- 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: The lesser value of Isat or Irms.

Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils; handle carefully to prevent damage.
- Bending: Do not excessively bend terminals to prevent wire fracture.
- Cleaning: Do not rinse coils; contact the manufacturer if cleaning is required.
- Magnetic Fields: Keep away from magnets or magnetic objects.
- Preheating: Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Perform within specified conditions to avoid short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is applied.
- Non-Magnetic Shield Type: Careful coil layout on the PCB is necessary to prevent malfunctions due to magnetic interference.
