INDUCTOR SATURATION
The condition which exists when an inductor cannot hold any
more magnetic flux. When an inductor saturates, the induc-
tor appears less inductive and the resistive component domi-
nates. Inductor current is then limited only by the DC resis-
tance of the wire and the available source current.

OPERATING VOLT MICROSECOND CONSTANT (E • T
The product (in VoIt • µs) of the voltage applied to the inductor
and the time the voltage is applied. This E • T
measure of the energy handling capability of an inductor and
is dependent upon the type of core, the core area, the num-
ber of turns, and the duty cycle.
