Discrete inductors combine like resistors, when connected in series or parallel. For example, inductors in series add and
inductors in parallel reduce in a way similar to Ohm’s Law.
Windings on the same magnetic core behave differently. Two windings in series result in four times the inductance of a
single winding. This is because the inductance varies proportionately to the square of the turns.
Paralleled VERSA-PAC windings result in no change to the net inductance because the total number of turns remains
unchanged; only the effective wire size becomes larger. Two parallel windings result in approximately twice the current
carrying capability of a single winding. The net inductance of a given PCM configuration is based on the number of
windings in series squared multiplied by the inductance of a single winding (L
is derived by multiplying the maximum current rating of one winding (I
