Using PTC thermistors at -40°C temperature should be their minimum operating temperature. There must not be an increase in temperature above 125°C for this thermistor to work. It has a total of 2 pins. A PTC thermistor could supply 32V voltage when it is in operation. A DC circuit cannot operate with a voltage above 32V. This DC circuit has thermistors having a voltage rating of 32V.
