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 between Isat and Irms.

Reminders for Using These Products:
- Storage: Within 12 months, at 5~40C and 35~65% RH.
- Environment: Avoid use or storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals due to hand oils; handle carefully to prevent damage.
- Soldering: Preheat components before soldering. Ensure temperature difference between solder and chip does not exceed 150C.
- Thermal Design: Account for self-heating when power is applied.
- Placement: For non-magnetic shielded types, consider coil placement on the PCB to avoid magnetic interference.
