FUSED SOLID ELECTROLYTE CAPACITOR PACKAGE

摘要

A fuse made of two exothermically alloyable metals, such as aluminum and palladium has electrical and thermal connection to a solid electrolyte 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 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.
