Wire Packing Factor in Magnetics Design

Packing factor is a quantity that appears in various places in electronics.
For example, the distribution of pixels on the faceplate of a video display
are made as dense as possible, to increase both resolution and active light-sourcing
area. The packing factor is the fraction of a total area that is used as
desired. Ideally, packing factor, kp
= 1.
In magnetics design, transductors (transformers or inductors) usually
contain windings of round wire in rectangular winding windows, of area Aw. To calculate the cross-section of total
conductor area within the window, it is necessary to know kp,
for the total conductive area.
