Abstract
An electrical component with a substrate having a planar surface. A capacitor is provided having a plurality of first plates and second plates wherein the first plates and second plates are non-contacting and in common planes. A plurality of third plates are parallel to the first plates and the second plates and interleaved between the planes. A first external termination is in electrical contact with the plurality of first plates and a second external termination is in electrical contact with the plurality of second plates. The capacitor is mounted on the substrate with the first plates, the second plates and the third plates perpendicular to the planar surface.
