Abstract

A fuse for a solid electrolyte capacitor is made of two exothermically alloyable metals such as aluminum and palladium. The fuse has a series electrical connection with and a thermal connection to the capacitor body. A defective and overheated capacitor section results in abnormally high currents so that the fuse temperature is elevated by ohmic self-heating and/or by the flow of heat from the overheated body. When the alloying temperature of the fuse is reached, the temperature of the alloying fuse momentarily becomes very high and opens essentially along its entire length.
