For protection, PTC thermistors are contained in Radial packages. In general, the PTC thermistors should be set to -40°C as their minimum operating temperature. A thermistor must not operate at temperatures exceeding 125°C in order for it to function properly. It is terminated with 2. The thermistor has a maximum of 2 pins. In the event that the PTC thermistors are operating, they can deliver 80V voltage. PTC thermistors are designed for 3A current. This is due to the fact that these thermistors have been rated for voltages of 80V in DC circuits. A PTC thermistor should not have a current above 3A. A reliable operation of this thermistor depends on the maximum voltage supplied by it.
