Abstract: Methods of construction for inductive components such as inductors, chokes, and transformers enable these components to be fabricated using mass production techniques, thereby avoiding the need to handle discrete devices during the manufacturing process. In one preferred embodiment, holes are formed through a ferromagnetic substrate and plated with conductive material. The arrangement of these holes, and the subsequent design that ensues, will form the inductive components within the plane of the media in which the device is formed; using the substrate for a magnetic core. By using this approach, the inductive components can be miniaturized to physical sizes compatible with the requirements of modern surface mount technology (SMT) for integrated circuitry (IC). In another preferred embodiment, a series of thin, concentric high permeability rings are etched on a substrate to provide high permeability transformers and inductors having minimal eddy current effects.
