TR165 SERIES 231.5K OHM THERMISTORS
231KOhm@25°C   ·   Type: NTC   ·   Curve: Fenwall Curve 16

A thermistor is a "thermally sensitive resistor". It is a widely used fundamental electrical component. A thermistor is sensitive and reasonably priced. It does not require the cold junction of a thermocouple, and it is generally faster than Platinum RTD.
