A miniature fuse has a housing consisting of a plastics base (1), a plastics cap (2), and two conductors which pass through the base and are bridged across inside the cap by a fusible conductor (3). The interior of the fuse housing is fully or partially lined with a ceramic-based lining (5) to protect the plastics against thermal decomposition and to promote condensation of the fusible conductor which may be evaporated, upon blowing of the fuse, to reduce internal pressure in the housing and hence avoid separation of the cap from the base and exposure of conductive parts.
