NTC 47k β3950 thermistor chart: resistance table (°C)

Resistance in ohms of an NTC thermistor with R₂₅ = 47kΩ and β = 3950 K, calculated with the Beta model from -40 °C to 125 °C. Real parts follow their manufacturer’s R/T table, which can differ from the Beta model by a few percent far from 25 °C; use these values for design estimates and check critical points against the datasheet.
