TR91 SERIES 10K OHM THERMISTORS

TR91 SERIES 10K OHM THERMISTORS

10KOhm@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.
