A subminiature fuse comprising two terminals, a substrate, a fusible conductor, ceramic coating, a second coating and a unitary housing. A ceramic substrate 80 plated at both ends is inserted into fingers (70) in terminal, a fusible wire element 10 is strung between the fingers (70) and (20, 30) and electrically connects the terminal (20, 30). The assembly 160 is encased in a ceramic adhesive 180 which is encased in a second material (200) with superior dielectric properties. The ceramic encased assembly is enclosed in a unitary housing by injection molding.
