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 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 60 40 30 20 10 0 - 10 - 20 - 30 - 40 - 50 50 A5 0 70 TOLERANCE (± %) 8 TEMPERATURE (°C) Fig. 1 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 “Standard Electrical Specifications for Curve Tracking Thermistors” table. To specify, add the appropriate suffix from the following table to the part number.

Since these thermistors have only one controlled point of reference (the point match temperature), the resistance at other temperatures is given by the specific curve resistance vs. temperature ratio. POINT MATCH TOLERANCES VS. TEMPERATURE Point match resistance tolerances at temperatures other than 25 ºC are not the same as at the calibration temperature. This difference is presented in figure 2. MAX. R vs. T RESISTANCE MIN. R vs. T NOMINAL R vs. T The tolerance at any given temperature is the point match tolerance plus a manufacturing tolerance depending on the specific curve. PIVOT POINT (CALIBRATION TEMPERATURE) 25 °C TEMPERATURE Fig. 1 DESIGN-IN SUPPORT A spreadsheet is available for the Vishay thermistor part numbers that gives you the resistance vs temperature data, the temperature coefficients and accuracy levels at any given temperature range and step.
