Terminology

Base Resistance - The resistance value of a thermistor at a specified temperature with negligible electrical power to avoid self heating.Usually base resistance will be defined at 25 C.

BETA - BETA(25ºC/85ºC) is a "material constant" that defines the Resis.-Temperature curve slope. It is calculated using the following equation: [(lnR25-lnR85)/(1/T25-1/T85Note: Absolute Temperature in degrees Kelvin(ºK)   must be used(ºC + 273.15) in the calculation.
