Why are there two ratings for the rated current of power inductors?

The rated current of power inductors is determined by two methods: the “rated current based on self‑heating, Irms,” and the “rated current based on the rate of change of inductance, Isat,” each of which carries significant importance. The “rated current based on self‑heating, Irms,” specifies the maximum allowable current according to the component’s heat generation; exceeding this limit may result in component damage or system failure.
