Abstract

A fusible element component for use in an electrical fuse, the component including a substrate made of insulative material and having a substrate surface, a fusible element made of a thin film of conductive material that is supported on the substrate, overlies a fusible element support area of the substrate surface, and provides a conductive path during normal current conditions, and a resistance element of resistance element material that is supported on the substrate, overlies a resistance element support area of the substrate surface that is a different area of the substrate surface than the fusible element support area, and is electrically in parallel to the fusible element to provide a shunt path during clearing of the fusible element during overcurrent conditions.
