ABSTRACT:
An electrical component, particularly a fuse for a surface-mount component, is formed by sputtering an aluminum conductor onto a square tube, sleeving the tube into an outer tube, filling the assembly with a room-temperature vulcanizing silicone sealant, cutting the assembly into segments, and metallizing the ends of each segment. In one embodiment, the sleeved tubes are mechanically separated from the surrounding silicone. In another embodiment, the silicone-coated tubes are mechanically separated from the outer tubes. In another embodiment fuses are made by sputtering the conductors onto a thin glass substrate, covering a link portion of the conductors with silicone adhesive, and dicing the substrate.
