High voltage capacitors

Abstract

In a method of manufacturing a multilayer ceramic component, a ceramic capacitor body is formed from electrode layers and dielectric layers. First and second external terminals are attached on opposite ends of the ceramic capacitor body. The ceramic capacitor body is coated to assist in increasing breakdown voltage. The electrode layers include active electrode layers configured in an alternating manner such that a first end of the active electrodes extends from one end of the ceramic capacitor body inwardly and a next internal active electrode extends from an opposite end of the ceramic capacitor body inwardly. The active electrode layer includes side shields to provide additional shielding.
