Abstract
A planar transformer wherein a conformal dielectric epoxy composition is provided on the planes containing the primary and secondary windings to encapsulate the windings and to insulate the windings from the perimeter of each plane to prevent the primary windings from electrically contacting the secondary windings around the edges of the planes. Also, a conformal dielectric epoxy composition separates the plane with the primary windings from the plane with the secondary windings from primary and secondary circuits directly and below windings.
