Resistance - Temperature Tables

Resistance - Temperature TableRatio is the resistance at temperature divided by the resistance at 25°C. To find the actual resistance value at the temperatures listed in thecharts, multiply the R25 value by the number listed in the Ratio column next to the corresponding temperature.As an example, a Curve A thermistor with a temperature tolerance of ±1°C over the temperature range 0° to 70°C would have the followingresistance tolerance: 0°C = ±5.1%; 25°C = ±4.4%; 70°C = ±3.4%NTC (Negative Temperature Coefficient) is the negative percent resistance change per degree C. To determine the resistance tolerance of aprecision thermistor at any temperature point multiply the temperature tolerance times the NTC.Curve ACurve BCurve CCurve DCurve E$ at 25°C/85°C3977K3942K3695K4262K4434K$ at 0°C/50°C 3892K 3813K 3575K 4141K 4276KTypical R25 = 1K to 100KTypical R25 = 10K to 100KTypical R25 = 5K to 20KTypical R25 = 25K to 100KTypical R25 = 1K to 200KTemperature°CRT/R25 RATIORT/R25 RATIORT/R25 RATIORT/R25 RATIORT/R25 RATIORATIONTCRATIONTCRATIONTCRATIONTCRATIONTC-50-45-40-35-30-25-20-15-10-5051015202530353740455055606570758085909510010511011512012513013514014515067.1347.2633.6924.2917.7113.059.7117.2975.5344.2343.2662.5401.9911.5721.2491.0000.80560.65300.60140.53250.43670.36010.29850.24870.20820.17520.14800.12560.10710.091610.078700.067860.058730.051000.044440.038850.034080.029970.026450.023400.020760.014877.16.96.76.46.26.05.85.65.45.35.15.04.84.74.54.44.34.14.14.03.93.83.73.63.53.43.33.23.23.13.02.92.92.82.72.72.62.52.52.42.42.356.3940.5629.4821.6416.0311.999.0406.8755.2704.0713.1682.4831.9591.5561.2441.0000.80880.65790.60660.53800.44230.36540.30340.25310.21210.17850.15080.12800.10910.093270.080060.068970.059620.051710.045000.039280.034390.030200.026600.023490.020800.018466.76.56.36.15.95.75.65.45.25.14.94.84.74.54.44.34.24.14.04.03.93.83.73.63.53.43.33.23.23.13.02.92.92.82.82.72.62.62.52.52.42.444.1332.3623.9717.9213.5210.297.8916.1024.7543.7312.9492.3461.8791.5141.2271.0000.81960.67540.62600.55940.46550.38930.32700.27600.23380.19900.17000.14570.12540.10840.093920.081680.071270.062370.054760.048210.042570.037690.033460.029790.026580.023776.36.15.95.35.65.45.25.14.94.84.64.54.44.34.14.03.93.83.83.73.63.53.43.43.33.23.13.03.02.92.82.82.72.62.62.52.52.42.42.32.32.282.3657.3040.3428.7220.6715.0211.038.1746.1134.6113.5072.6892.0771.6171.2671.0000.79430.63490.58150.51060.41300.33590.27470.22590.18660.15490.12930.10830.091150.077040.065380.055700.047640.040890.035220.030450.026410.022980.020060.017560.015420.013587.47.16.96.76.56.36.15.95.75.65.45.25.14.94.84.74.54.44.44.34.24.14.03.93.83.73.63.53.43.33.23.23.13.02.92.92.82.82.72.62.62.589.6962.2543.6930.9822.2016.0611.738.6446.4254.8163.6382.7702.1251.6421.2771.0000.78810.62500.57060.49860.40010.32280.26190.21360.17500.14410.11930.099150.082780.069410.058440.049400.041920.035710.030530.026190.022540.019470.016870.014670.012790.011187.47.27.06.86.66.46.26.05.85.75.55.45.25.15.04.84.74.64.54.54.34.24.14.03.93.83.73.73.63.53.43.33.23.23.13.03.02.92.82.82.72.7(775) 674-5100 (800) 257-3526 FAX (775) 674-5111 E-mail: sales@selcoproducts.comwww.selcoproducts.com
