For the diode style "DO-35" packaged thermistors, the thermistor chip is held between two lead wires in an axial fashion. A glass sleeve is placed around the assembly and the assembly is heated to an elevated temperature where the glass sleeve melts around the thermistor chip and seals to the lead wires. As in diode construction, the pressure that the glass exerts on the assembly provides the ...

This is a thermistor that at room temperature has about 100KΩ of resistance and when exposed to very hot temperatures has a resistance in the range of 30KΩ. Thus, there is a significant drop in resistance. We will exploit this principle with a voltage comparator to build a circuit that can sense and react to these temperature …
2020-09-16· Furthermore, NTC thermistor resistances at 25 °C are significantly higher than those of the PTC variety. The most common NTC thermistors are 10k and 100k ohms, where PTC are 470 ohms and 1k ohms. Tolerances for PTC thermistors can commonly be 50%, which will not provide an accurate temperature reading without accurate calibration.
