Radial includes it as a convenience. NTC thermistors are reliable when operating at 170°C. NTC thermistors can operate at -55°C for relability. NTC thermistors have a total of 2 terminals. The 2 pins of the NTC thermistors must be connected to make the thermistors work correctly. Fuse elements can tolerate a maximum current of 9.5A without too much deterioration. A NTC thermistor should have a supply voltage of 265V for maximum efficiency.
