Abstract
A ceramic substrate is provided with a plurality of planar conductors formed on a surface of the substrate; conductors extend substantially radially from an imaginary point on the surface of the substrate. A layer of dielectric material is formed over the major portion of each of the conductors to form a ring of dielectric material to which a ferrite toroidal core is adhesively secured. The core is precoated with an insulating material prior to adhesively being secured to the dielectric ring. A plurality of wire conductors are wire bonded at each end thereof to the exposed ends of the metal conductors on the substrate.
