NTC 10k β3977 thermistor chart: resistance table (°F)
Resistance in ohms of an NTC thermistor with R₂₅ = 10kΩ and β = 3977 K, calculated with the Beta model from -40 °F to 257 °F. 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.
Each row is a 10-degree step; the column adds the units digit (subtracts it in rows below zero). Example: 100 + 5 → 105 °F.
