Abstract
A multilayer, ceramic dielectric power capacitor made of plural layers of thin films of dielectric material having a thickness between 20 and 200 microns and a dielectric strength which is greater than that of thick layers, but which reduces the volume of the capacitor. Formed on each dielectric thin film is a conductive foil having a thickness between 2 and 10 microns. The thickness of the dielectric films is quite thin to reduce the volume of the capacitor, while that of the foils is thick, as compared to the prior art, to facilitate removal of heat. An anti-corona groove is provided to protect the connections at the capacitor terminals. The capacitor is useful in high frequency generator applications.
