Abstract

A low profile electrical transformer (10) comprises at least two electrical windings (14) and a ferromagnetic base member (12). The base member is an integral construction presenting a core structure and a plurality of termination structures. The electrical windings are arrayed about the core structure and present a plurality of lead structures which are attached with the termination structures for electrical attachment in a circuit. A method for making the low profile transformer having an electrical winding structure including at least electrical windings and a plurality of termination structures; and a base member having a plurality of termination sites; comprises the steps of: (a) assembling the electrical winding structure and the base member; and (b) during the assembling, attaching the plurality of electrical termination structures with at least some of the plurality of termination sites to present a plurality of electrical termination loci for connection within an electrical circuit.
