It is important to protect PTC thermistors from damage by placing them in Radial packages. It is advisable to set the PTC thermistors to -40°C as the minimum operating temperature. A temperature of 125°C should not be exceeded during operation of this thermistor. 2 is the termination of the PTC thermistor. These thermistors have 2 pins. PTC thermistors could operate at 80V voltages. The PTC thermistors are designed for a 700mA current. When using PTC thermistors, the current shouldn't exceed 700mA. This thermistor must be operated at 80V voltage in order to be reliable.
