An example of the resistance tolerance at various temperatures for the two different tolerancing methods is described in the following graph: ± 5 % POINT MATCH CURVE 10 9 TOLERANCE (± %) 8 7 25 °C 6 ± 1 °C CURVE TRACK CURVE 5 4 A2 3 A8 A3 2 A4 1 150 130 140 120 110 100 90 80 70 60 50 30 20 10 0 - 10 - 20 - 30 - 40 - 50 40 A5 0 TEMPERATURE (°C) CURVE TRACKING TOLERANCE Thermistors are calibrated at the high temperature of the curve track range and then final tested at the low temperature of the curve track range. This ensures that the thermistor will meet the specified temperature accuracy at every temperature within the desired temperature range. Several temperature ranges are available and the accuracy of the thermistor may be ± 0.2 °C, ± 0.5 °C, and ± 1.0 °C. The Curve Tracking temperature ranges and their code designators are shown in Figure 1 and Table 1. To specify, add the appropriate suffix from the following table to the part number. Example: 1M1002-B3 = Curve 1, 10 kΩ at + 25 °C, curve tracking to ± 0.5 °C from 0 °C to + 70 °C STANDARD ELECTRICAL SPECIFICATIONS FOR CURVE TRACKING THERMISTORS TEMP. RANGE TOLERANCE PART NO.

Since these thermistors have only one controlled point of reference (the point match temperature), the resistance at other temperatures is given by the "Resistance vs. Temperature Conversion Tables" for the appropriate material curve. The resistance value at any temperature is the ratio factor times the resistance at 25 °C. Example: 1M1002-5, + 70 °C resistance = (Resistance factor for curve 1 at 70 °C is 0.1990) x (10 000 W resistance at 25 °C) = 1990 Ω. The tolerance of the resistance at any temperature is described by Figure 2. FIGURE 2 POINT MATCH TOLERANCES VS. TEMPERATURE Point match resistance tolerances at temperatures other than 25 ºC are not the same as the calibration temperature. This difference is presented in Figure 2. MAX. R vs. T RESISTANCE MIN. R vs. T NOMINAL R vs. T PIVOT POINT (CALIBRATION TEMPERATURE) The tolerance at any given temperature is the point match tolerance + the MT ± % (Manufacturing Tolerance). The MT ± % may be obtained from the R vs. T Conversion tables and is added to the point match temperature, i.e., ± 1 % Tol. at 25 ºC + ± 2.6 % at - 30 ºC for Curve 1 equals a total tolerance of ± 3.6 % at - 30 ºC. 25 °C TEMPERATURE COMPUTER AIDS FOR THERMISTOR SELECTION A spreadsheet is available for the Vishay Thermistor Materials that calculates Beta, Steinhart-Hart Equation Constants A, B, and C, the resistance at any temperature based upon the Steinhart constants or Beta, the temperature equivalent of the resistance reading, and resistance temperature coefficients. This spread sheet will also calculate the total resistance tolerance of any point matched thermistor for temperatures in 10 ºC increments, and the resistance tolerance at any temperature within the calibrated range of curve tracking thermistors.
