摘要： In a positive temperature coefficient thermistor, a terminal holding member is provided between an outer casing and an elastic terminal electrically connected to the semiconductor ceramic element. The terminal holding member is formed of a thermoplastic resin having a low softening point. Consequently, when an abnormally large amount of heat is generated in the semiconductor ceramic element, the terminal holding member melts and deforms, causing the semiconductor ceramic element to be separated and thereby electrically disconnected from the terminal.

摘要： An electric protective circuit includes an electric fuse and an electric resistance loop connected in series with the fuse, the fuse and loop being mounted on a substrate. The fuse includes a solder that is connected as a resistance in a current series circuit between connection terminals and that melts at elevated temperatures caused by heating of the substrate. The solder is surrounded by a material that protects the solder against oxidation by the surrounding air and completely covers the solder, enabling the solder to contract onto the connecting terminals when it melts and break the current path. The material is temperature-stable in a solid state of normal fuse operating temperatures and includes one or a combination of waxes, resins, thermoplastics, and synthetic fluxes. The material is applied in a region or area surrounding the solder that is delimited by barrier walls that prevent the material from running away from the region. The resistance loop includes current-conducting paths that are mutually connected with bridging elements whose electrical resistance is much lower than the electrical resistance of the current-conducting paths. The resistance loop includes trimming elements for adjusting the resistance of the resistance loop.
