Abstract
A blank formed from electrically conductive sheet material defines a continuous conductive path which includes two terminal ends and at least three loops disposed along the path. The blank is foldable at preselected folding locations on the path to position the loops in overlying relation to one another, and the blank is preferably formed with the loops disposed along the conductive path in substantially the same plane. The blank is used to form a multi-turn planar winding for a magnetic device such as, for example, an inductor or transformer which may be incorporated into electrical circuits such as power supplies. The planar magnetic device provides a low overall volume and profile, as well as a substantially higher volume or surface area of conductive material per turn of the winding compared to conventional wire or etched windings to provide a higher current carrying capacity and fewer turns compared to conventional windings.
