Abstract

An electric capacitor particularly for use as a high frequency power capacitor, and provided with liquid cooling, the capacitor having separated metal layers as its plates and the metal layers being separated by a densely sintered ceramic dielectric body, one embodiment of which is generally pot-shaped. Heat generated in the capacitor is dissipated by cooling liquid which is directed by a jacket surrounding that one metal layer to pass over the metal layer and dissipate the heat. The metal layer is comprised of a silver frit. To avoid the metal layer being eroded by the cooling liquid, a layer of glaze, which is resistant to the cooling liquid and whose coefficient of expansion is similar to that of the dielectric body covers over the metal layer in contact with the cooling liquid.
