Abstract
A multi-component transformer to be used in conjunction with surface mounting technology. Transformer windings are provided by a plurality of conductors arranged in parallel and disposed around a ferrite core. A portion of the winding is disposed in a spacer member or alternatively is formed from tracings of a circuit board. A portion of a ferrite core is disposed above the conductors. Then a bridge member, which is U-shaped and has a plurality of conductors disposed in a dielectric body, is disposed to overlie a portion of the magnetic core overlying the first tracings. The conductors of the bridge member are coupled to the underlying tracings such that the tracings form a continuous loop around a portion of the magnetic core to function as a winding of a transformer. Alternative embodiments are disclosed in which variations of the multi-component provides variations in the design.
