PTC thermistors are packaged as 0402 units to prevent damage. A safety package is used to safeguard these PTC thermistors. It is recommended to set the minimum operating temperature of the PTC thermistors at -40°C. Ensure this thermistor is working at 125°C by keeping its operating temperature below that. As you can see, this thermistor has 2 pins. As a result, PTC thermistors may supply 32V voltage at all times. As long as the DC circuit uses a thermistor, the voltage supplied by the thermistor should not exceed 32V.
