ABSTRACT:
A high-Q printed circuit board inductance comprises a ferromagnetic core placed through an aperture of a metallic support base of a printed circuit board. The ferromagnetic core provides a preferred path for time-varying magnetic flux. An overlayer of insulating material such as porcelain enamel is interposed between a planar printed coil structure located about the ferromagnetic core and the metallic support base. A gap is formed in the metallic support base and extends outwardly from the aperture in a manner intersecting closed paths within the metallic support base that are linked by the time-varying magnetic flux. A high-Q inductance is formed because the flow of eddy currents in the closed paths is substantially impeded across the gap.
