TOLERANCES AVAILABLE FOR TYPE M, C AND T THERMISTORS
DESCRIPTION OF THERMISTOR TOLERANCES
The many applications of thermistors have mandated the need for two basic tolerance schemes for these products - curve
tracking and point match thermistors. An example of the resistance tolerance at various temperatures for the two different
tolerancing methods is described in the following graph:
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: 01M1002SFB3 = Curve 1, 10 kΩ at + 25 °C, curve tracking to ± 0.5 °C from 0 °C to + 70 °C

POINT MATCH TOLERANCE
The standard leaded thermistors are calibrated and tested at 25 °C to a tolerance of ± 5 % or ± 10 %; however, tighter tolerance,
point matched thermistors are readily available as are special point match temperatures to fit your application.
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. The resistance vs. temperature conversion tables can
be found at: www.vishay.com/doc?33004 and www.vishay.com/doc?33011.
Example: 09M1002JF, + 70 °C resistance = (Resistance factor for curve 9 at 70 °C is 0.1990) x (10 000 Ω 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.
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 (see www.vishay.com/doc?33004) 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.
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. Please
contact factory if interested in this Excel™ spreadsheet at thermistor1@vishay.com.
