  • Method of manufacturing a surface-mounted fuse device
    Patent number: 5943764
    Abstract: A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate and terminal pads. The second subassembly includes a protective layer which overlies the fusible link so as to provide protection from impacts and oxidation. The protective layer is preferably made of a polymeric material. The most preferred polymeric material is a polyurethane gel or paste. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: August 31, 1999
    Assignee: Littelfuse, Inc.
    Inventors: Vladimir Blecha, Katherine M. McGuire, Andrew J. Neuhalfen, Daniel B. Onken
  • Surface-mounted fuse device with conductive terminal pad layers and groove on side surfaces
    Patent number: 5790008
    Abstract: A thin film surface-mount fuse having two material subassemblies. The first subassembly includes a fusible link, its supporting substrate with a groove on side surfaces and a plurality of conductive terminal pad layers. The second subassembly includes a protective layer which overlies the fusible link so as to provide protection from impacts and oxidation. The protective layer is preferably made of a polymeric material. The most preferred polymeric material is a polyurethane gel or paste. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.
