ABSTRACT:
An arc-resistant trimable monolithic ceramic capacitor is disclosed. The capacitor includes a surface electrode covered by a further dielectric layer, the further dielectric layer including an aperture registering with portions of the surface electrode, margins of the surface electrode being covered by the further dielectric layer. The capacitor may be trimmed, if necessary, by eroding portions of the surface electrode exposed through the aperture of the further dielectric layer. The covering dielectric layer prevents arc-over at the edges of the surface electrode and prevents changes in value of the finished capacitor by preventing portions of the surface layer from separating from the further dielectric layer.
