RT VALUE AND TOLERANCE
DETERMINATION OF THE
RESISTANCE/TEMPERATURE DEVIATION
FROM NOMINAL VALUE
These thermistors have a narrow tolerance on the B-value,
the result of which provides a very small tolerance on the
nominal resistance value over a wide temperature range. For
this reason the usual graphs of R = f(T) are replaced by
Resistance Values at Intermediate Temperatures Tables,
together with a formula to calculate the characteristics with a
high precision.
The total resistance deviation is obtained by combining the
‘R25-tolerance’ and the ‘resistance deviation due to
B-tolerance’.
When:
X = R25-tolerance
FORMULAE TO DETERMINE NOMINAL
RESISTANCE VALUES
Y = resistance deviation due to B-tolerance
Z = complete resistance deviation,
The resistance values at intermediate temperatures, or the
operating temperature values, can be calculated using the
following interpolation laws

Example: at 0 ∞C, assume X = 5%, Y = 0.89% and
TC = 5.08%/K (see Table ), then:
Rref is the resistance value at a reference temperature (in
