R
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.
FORMULAE TO DETERMINE NOMINAL
RESISTANCE VALUES
The resistance values at intermediate temperatures, or the
operating temperature values, can be calculated using the
following interpolation laws
(extended “Steinhart and Hart”):
where:
Formulae numbered and are interchangeable with an
error of max. 0.005 °C in the range 25 °C to 125 °C and
max. 0.015 °C in the range - 40 °C to + 25 °C.
