Adjustable multilayer capacitor

Abstract

A multilayer capacitor has a dielectric block with a marked position where the adjustable capacitance is to be placed. The capacitor has two end walls on which are first and second terminal electrodes. The electrodes have first and second narrow bands extending over marginal end portions of first and second side walls of the block. Two narrow spaced conductive stripes on the first side wall extend from the first band along lateral edges of the first side wall and terminate short of the second band to define a first rectangular U-shaped extension of the first terminal electrode on the first side wall. In the block are embedded spaced electrodes to determined the capacitance of the capacitor. A first stripe of conductive ink of any desired width can be applied to an uncovered area of the first wall to contact the U-shaped extension of the first terminal electrode to adjust capacitance of the capacitor. Two other conductive stripes applied to the second side wall to extend from the second band and terminate short of the first band to define a second U-shaped extension of the second terminal electrode. A second stripe of conductive ink can be applied to an uncovered area of the second wall to contact the second U-shaped electrode extension to further adjust the capacitance of the capacitor.
