Abstract
A thin film surface-mountable fuse for protection against electrical overload. The fuse comprises a substrate, fusible link, a containment compound, and a pair of terminal pads. The fusible link is produced from a first conductive material and supported on the substrate. A diffusion bar of a second conductive material is deposited on a portion of the fusible link. The containment compound is also deposited over a portion of the fusible link. The containment compound inhibits migration of the diffusion bar along the fusible link during an electrical overload. The terminal pads are electrically connected to the fusible link and also supported by the substrate.
