Inductance measured at 10KHz, 1Vrms 2. Isat is DC current at which the inductance drops the specified amount from its original value without bias. 3. Irms is the DC current that causes the specified temperature rise of the winding from 25°C ambient for the inductor. Revised 03/17/2016 Product performance is limited to specified parameters.
