NTC Thermistor Beta Value: Inputs and Datasheet Checks This page is a practical guide to selecting and checking an NTC thermistor beta value. It does not contain an interactive calculator. For an OEM design, the beta value must be tied to the sensor’s stated temperature interval and resistance–temperature (R/T) data; a single number cannot guarantee accuracy across every temperature. What the beta value describes An NTC thermistor’s resistance generally falls as temperature rises. The beta value (B, in kelvins) is a two-point approximation of the curve over a specified interval, for example B25/50. The interval matters: values calculated over different
