Fuse with thin film fusible element supported on a substrate
First Claim
1. A fusible element component for use in an electrical fuse, said component comprising,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 said substrate, overlies a fusible element support area of said substrate surface, and provides a conductive path during normal current conditions, anda resistance element of resistance element material that is supported on said substrate, overlies a resistance element support area of said substrate surface that is a different area of said substrate surface than said fusible element support area, and is electrically in parallel to said fusible element to provide a shunt path during clearing of said fusible element during overcurrent conditions.
