The Heating Current is the DC current which causes the component temperature to increase by approximately 50°C. This current is determined by soldering the component on a typical application PCB, and then applying the current to the component for 30 minutes. Isat is the saturation current at which inductance rolls off approximately 30% from its initial unbiased inductance value. PC Board layout, proximity of other components, trace size and airflow will affect temperature rise and must be considered when selecting an inductor.
