Note	N/A Inductance measured @ 100 KHz, 1 Vrms Isat is the DC current where the inductance drops the specified amount from its original value. Irms is the DC current that causes the specified temperature rise of the winding from 25 ºC ambient for the inductor without housing or potting. Aluminum case, thermal conductive epoxy, or thermal pads can be added to improve cooling.
