B-Constant R=R0 expB (1/T-1/T0) ..............(1) R: Resistance in ambient temperature T (K) (K: absolute temperature) R0: Resistance in ambient temperature T0 (K) B: B-Constant of Thermistor as (1) formula B= Rn (R/R0) / (1/T-1/T0) ............(2) 3. Thermal Dissipation Constant When electric power P (mW) is spent in ambient temperature T1 and thermistor temperature rises T2, there is a formula as follows P=C (T2-T1) ..................(3) C: Thermal dissipation constant (mW/°C) Thermal dissipation constant is varied with dimensions, measurement conditions, etc. 4. Thermal Time Constant Period in which Thermistor's temperature will change 63.2% of its temperature difference from ambient temperature T0 (°C) to T1 (°C). Resistance vs. Temperature !Basic Characteristics !Performance Thermal Time Constant Item Resistance Condition Measured by zero-power in specified ambient temperature. Rated Electric Power Shows the required electric power that causes Thermistor's temperature to rise to a specified temperature by self heating, at ambient temperature of 25 °C. Permissive Operating Current It is possible to keep Thermistor's temperature rising max. 1°C. Thermal Dissipation Constant Shows necessary electric power that Thermistor's temperature rises 1°C by self heating. It is calculated by next formula (mW/°C). B-Constant Calculated between two specified ambient temperatures by next formula. T and T0 is absolute temperature (K). Rn (R/R0) B = 1/T Y1/T0 P C = T YT0 102 101 –20 Temperature (°C) 0 20406080 120 100 10–2 10–1 1 B=3450 B=3900 B=4100 Basic Characteristics T1 T0 Time 63.2% X Please inquire about test conditions and ratings. |
