Abstract:
1. A center-electrode assembly comprising: a ferrite; center-electrode patterns and insulating films disposed on the top surface of the ferrite; a conductive pattern formed on the bottom surface of the ferrite; and connecting electrodes directly formed on sides of the ferrite; wherein the connecting electrodes electrically connect the center-electrode patterns and the conductive pattern; said connecting electrodes, said center-electrode pattern and said conductive pattern are comprised of at least one of a plated conductive material, a printed conductive material, a sputtered conductive material, a vapor deposited conductive material, and an applied paste conductive material formed directly on the sides, on the top surface and on the bottom surface, respectively, of the ferrite; the center-electrode patterns and the insulating films are alternately disposed such that each of the center electrode patterns includes a portion that is in direct contact with a respective one of the insulating films and another portion that is in direct contact with the top surface of the ferrite mother board; and the connecting electrodes are formed on grooves formed in the sides of the ferrite.
