The Radial package contains it for your convenience. NTC thermistors are capable of reliable operation at a maximum operating temperature of 170°C. In order to ensure reliability, NTC thermistors can be operated at a minimum temperature of -55°C. Total number of terminations on these NTC thermometers is 2. To make an NTC thermistor work properly, it needs to have the 2 pins connected. If the thermistors are operated at 5.1A, the fuse element will not deteriorate too much. To maximize the efficiency of the NTC thermistors, the supply voltage should be set to 230V.
