ABSTRACT:
A tubular capacitor is formed as follows. A ceramic tube comprising an outer ceramic cylinder and a plurality of radial walls is extruded. The extruded body may also include a second ceramic cylinder coaxial with the first. The one or more cylinders and the radial walls form a plurality of longitudinal passages. After the extrudate is fired and cut, the surfaces of the passages and the remaining surfaces of the cylinder or cylinders are metallized. Selected regions of metalization are removed to form discrete electrodes. The end terminations each comprise a base member from which there extends a plurality of prongs. Some of the prongs extend into the longitudinal passages, whereas others make contact with the outer surface of the outer cylinder and the inner surface of the inner cylinder.
