To prevent damage to the PTC thermistors, they are packaged in SMD/SMT packages. Temperature -40°C is the minimum operating temperature for PTC thermistors. This thermistor must not operate above 85°C in order for it to work. Its terminations are 2. A PTC thermistor could provide 6V voltage when operating. In the PTC thermistors, 100A is the current they are designed to handle. When PTC thermistors produce heat, they should be at 600mW.
