  • Manufacturing method for a PTC thermistor
    Patent number: 5351390
    Abstract: PTC (positive temperature coefficient) thermistors of a novel configuration and a method for their manufacture. The PTC thermistors have a PTC element sandwiched between two electrodes for which leads are formed as an extension of each of the two electrodes protruding beyond the edge of the PTC element. Several manufacturing methods avoid undue thermal and physical stress to the PTC composition while providing PTC thermistors having a variety of shapes and configurations.
