Note	N/A Inductance test @ 10 KHz, 1 Vrms Isat is DC current at which the inductance drops the specified amount from its original value without bias. Irms is the DC current that causes the specified temperature rise of the winding from 25ºC ambient for the inductor. Add V for Vertical Mount, H for Horizontal Mount
