Note on Current Ratings:
- Saturation Current: DC current at which inductance drops 30% from its value without current.
- Temperature Rise Current: 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.
- Component temperature is affected by circuit design, component placement, PCB trace size/thickness, airflow, and other cooling provisions. End-application verification of part temperature is recommended.
