(2) dc resistance is measured at 25c. (3) the heating current is the dc current, which cause the component temperature to increase by approximately 50c. this current is determined by soldering the component on a typical pcb, and then apply the current to the component for 30 minutes. (4) isat is the saturation curren t at which inductance rolls off approximately 30% from its initial unbias inductance value. (5) box layout, proximity of other component, trace size and airflow will affect temperature rise and must be considered when selecting an inductor.
