Abstract: A fuse includes a housing with opposing first and second ends and a first and second fusible element. It also includes first and second ferrules made from aluminum alloy, each electrically connected to the corresponding first and second fusible element. Each ferrule features a side wall and an end wall, with the end wall extending from the side wall to close the first or second end of the housing. Additionally, the end wall includes a boss that extends toward the interior of the housing. Together, the side and end walls form an interior receptacle designed to accommodate the first or second end of the housing.

Abstract: A high-capacity miniature cartridge fuse is provided. The fuse includes a housing, a fusible element, and first and second ferrules fabricated from aluminum alloy. The aluminum alloy ferrules is fabricated to withstand high pressure generated inside the housing as a result of arcing and to stay in place after repeated temperature and pressure changes caused by at least one of i) current or ii) arcing during short circuit events. The aluminum alloy plated with a first metal plating fabricated from a first metal different from the aluminum alloy and a second metal plating fabricated from a second metal different from the first metal, the second metal plating overlaying the first metal plating. Each of the first and second ferrules includes a side wall and an end wall, wherein the end wall includes a boss extending toward an interior of the housing.

Abstract: Electromagnetic inductor components include a magnetic core and a conductor assembled with the core and defining a winding completing a number of turns. The conductor is fabricated from a composite material including carbon nanotubes having an improved conductivity. The conductor has a cross section defined by an effective diameter. The conductor is fabricated to have performance parameters that are selected in view of a function of a ratio of conductivity and/or a function of a ratio of effective diameter of the composite conductor material relative to a reference conductor material as conventionally used in an inductor fabrication.
