9 Based on complex titanate chemical compositions (BaTiO3, SrTiO3, etc.), their specific performance is created by the addition of dopants and unique processing, including high force pressing into desired shapes and precision sintering. After the creation of the PTCR pellets, highly specialized metallurgical techniques are employed to create low ohmic contact systems. These electrodes are bonded to the ceramic with glass frit to provide great strength and high current carrying makes the PTCR such a useful device is its Resistance versus Temperature characteristic. It exhibits a low resistance over a wide temperature range, but upon reaching a certain temperature it undergoes a dramatic increase in resistance (several orders of magnitude).

10 This temperature is called the Curie Temperature or Switching Point . The increase in temperature can be caused by internal heat (I2R loss) or from external ambient temperature increases. In applications, this rate of temperature change is often controlled to provide a time delay function. When the source of the heat is removed, the PTCR returns to its initial base resistance. As completely tested pellets for assembly into custom packages, utilizing high pressure mechanical contacts for refrigeration compressor motor starting and telecommunication overcurrent protection. As components with wire leads for fluorescent lighting and electronic overcurrent protection unique properties of the PTCR ha
