Abstract: An inductive component includes a core and the core contains at least one winding of coated ferromagnetic wire, wound in a first direction. The coated ferromagnetic wire includes a dielectrically resistive coating, for example a glass coating, provided around a ferromagnetic center having a substantially round cross-section. The inductive component also includes a signal conductor wound around at least a part of the core in a second direction that is different than the first direction. In one embodiment, the dielectrically resistive coating is a glass coating provided around the ferromagnetic center in the coated ferromagnetic wire wound to form the core, and the signal conductor is wound perpendicular to the coated ferromagnetic wire windings in the core.
