Abstract: The present invention provides a multi-layer capacitor. It has internal electrodes extending over a part at least of each layer and connected electrically and thermally alternately to one or other of two terminals extending over a junction edge of the capacitor and over a part at least of a lateral edge adjacent said junction edge. To each of the terminals is soldered an electrical connection adapted to provide also heat drainage. Such a structure improves the drainage of the heat dissipated in the capacitor during operation under high reactive power or at high frequency.

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.
