ABSTRACT:
A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate with a groove on side surfaces and a plurality of conductive terminal pad layers. The second subassembly includes a protective layer which overlies the fusible link so as to provide protection from impacts and oxidation. The protective layer is preferably made of a polymeric material. The most preferred polymeric material is a polyurethane gel or paste. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.
