ABSTRACT:
A monolithic capacitor whose capacitance can be varied by removing part of an electrode. The capacitor may comprise an end termination, coupled to a plurality of internal electrodes which are disposed in a dielectric, and a top electrode which is disposed on one side of the dielectric. If a part of the top electrode is removed, the capacitance of the monolithic capacitor is changed, without an unacceptable change in "Q". The top electrode may be disposed so that a part of it may be removed with an energy beam device, such as a laser or a particle beam.
