ABSTRACT:
A multilayer ceramic dielectric capacitor comprises a plurality of layers of dielectric arranged in a stack. Between the dielectric layers are arranged metallic electrodes. Alternate electrodes in the stack extend to opposite end faces thereof, where they are electrically connected by end terminations. The electrodes each comprise a plurality of parallel conductive elements provided between two adjacent dielectric layers. The adjacent dielectric layers are bonded together along three of their edges and at the gaps between the conductive elements, thus providing a stronger structure than when the adjacent layers are only bonded at the three of their edges. The electrode pattern comprised by a plurality of parallel elements is particularly applicable to metal-impregnated ceramic dielectric capacitors, which employ fugitive electrodes that are burnt away during firing of the ceramic to leave spaces for subsequent metal impregnation.
