DESCRIPTION
These thermistors have a negative temperature coefficient.
The device consists of a chip with two solid copper tin
plated leads. It is grey lacquered and color coded, but not
insulated.
PACKAGING
The thermistors are packed in bulk or tape on reel; see code
numbers and relevant packaging quantities.

VALUE AND TOLERANCE
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.

DETERMINATION OF THE
RESISTANCE/TEMPERATURE DEVIATION
FROM NOMINAL VALUE
The total resistance deviation is obtained by combining
the “R
25
-tolerance” and the “resistance deviation due to
B-tolerance”.
When:
X =
R
25
-tolerance
Y = resistance deviation due to B-tolerance
Z = complete resistance deviation,

The temperature tolerances are plotted in the graphs on the

Example:
at 0 °C, assume X = 5 %, Y = 0.89 % and
