Note:

1.

Inductance measured at 10KHz, 1Vrms

2.

Isat is the DC current where the inductance drops the specified amount from its original value.

3.

Irms is the DC current that causes the specified temperature rise of the winding from 25°C ambient for the inductor without housing or potting. Aluminum case, thermal

conductive epoxy, or thermal pads can be added to improve cooling.
