Abstract

A fuse component includes an electrically insulating substrate having a top surface, a thick film fuse element applied to the top surface and a cover layer. The cover layer is made of an electrically insulating material having good caloric conductivity. The cover layer can be directly applied to the thick film fuse element and the adjoining zones of the top surface of the substrate. The cover layer can contain a glass having a specific caloric conductivity of >2 W/mK. The cover layer can have a window disposed above a section of the fuse element, the section of the fuse element located within the window being at least partially covered by a solder containing layer.
