    摘要： A bulk capacitor includes a first electrode formed of a metal foil and a semi-conductive porous ceramic body formed on the metal foil. A dielectric layer is formed on the porous ceramic body for example by oxidation. A conductive medium is deposited on the porous ceramic body filling the pores of the porous ceramic body and forming a second electrode. The capacitor can then be encapsulated with various layers and can include conventional electrical terminations. A method of manufacturing a bulk capacitor includes forming a conductive porous ceramic body on a first electrode formed of a metal foil, oxidizing to form a dielectric layer and filling the porous body with a conductive medium to form a second electrode. A thin semi-conductive ceramic layer can also be disposed between the metal foil and the porous ceramic body.

    摘要： An electronic component such as a capacitor includes a substrate having first and second principal surfaces, a dielectric layer overlaying the first principal surface of the substrate, a first electrode, and a second electrode. There is a passivation layer overlaying the first and second electrodes, a first opening being formed in the passivation layer over the first electrode and a second opening being formed in the passivation layer over the second electrode. A first bottom electrode termination is positioned in the first opening and a second bottom electrode termination is positioned in the second opening. The first bottom electrode termination is electrically connected to the first electrode and the second bottom electrode termination is electrically connected to the second electrode. A standoff is positioned between the first bottom electrode termination and the second bottom electrode termination and attached to the passivation layer to thereby provide support for the electronic component when mounted. The standoff provides resistance to tilting.
