TOLERANCES AVAILABLE FOR TYPE T, M, AND C 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
“Standard Electrical Specifications for Curve Tracking Thermistors” table.
To specify, add the appropriate suffix from the following table to the part number.
Example: 01M1002SFB3 = curve 1, 10 k 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 specific curve resistance vs. temperature ratio.
Vishay Dale
POINT MATCH TOLERANCES VS. TEMPERATURE
Point match resistance tolerances at temperatures other
than 25 °C are not the same as at the calibration
temperature. This difference is presented in Fig. 2.
The tolerance at any given temperature is the point match
tolerance plus a manufacturing tolerance depending on the
specific curve.

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. The Steinhart & Hart formula and
coefficients A, B, and C are shown as well. This data can be obtained by visiting the Vishay NTC curve computation page at:
