Abstract
A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate and terminal pads. 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 polycarbonate adhesive. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.
