(2) The Heating Current is the DC current which causes the component temperature to increase by approximately 40C from 25C ambient. This current is determined by soldering the component on a typical application PCB, and then applying the current to the component for 30 minutes. Heating current in both winding is under series configuration. (3) Isat is the saturation current at which inductance rolls off approximately 30% from its initial unbiased inductance value. It is sum of current flowing on both winding (parallel configuration). (4) PC Board layout, proximity of other components, trace size and airflow will affect temperature rise and must be considered when selecting an inductor.
