Abstract
A reduced barium titanate ceramic capacitor in the form of a rod has closely-spaced electrodes connected in parallel or two spiraled electrodes on the surface thereof and a dielectric layer underneath each. By reducing both the distance between adjacent electrodes and the width of the electrodes, a capacitor with a low power factor is obtained.
Claims7
A capacitor comprising a semiconductive cylindrical body of reduced ceramic material, a plurality of closely-spaced, substantially parallel, interdigitated metal electrodes disposed on the cylindrical surface of said body, said body having a thin dielectric layer of an oxidized state of said ceramic material immediately beneath each of said electrodes, and a terminal disposed over each end of said cylindrical body, each said terminal in contact with at least one alternate of said interdigitated electrodes.
