So this approach is only suitable for describing a restricted range around 1 the rated temperature or resistance with sufficient accuracy. NTC resistance in Ωat temperature T in K 2 For practical applications a more precise description of the real NTC resistance in Ωat rated temperature in K R/T curve may be required. Either more complicated approaches (e.g Temperature in K the Steinhart-Hart equation) are used or the resistance/ temperature relation as given in tabulated form. The below table B value,material-specific constant of the NTC thermistor has been experimentally determined with utmost accuracy for temperature increments of 1 degree.
