FEATURES
Accuracy over a wide temperature range
High stability over a long life
Excellent price/performance ratio
APPLICATIONS
Temperature sensing and control
These thermistors have a negative temperature coefficient.
The device consists of a chip with two tinned solid
copper-plated leads. It is grey lacquered and colour coded,
but not insulated.
PACKAGING
The thermistors are packed in bulk or tape on reel;
see code numbers and relevant packaging quantities.

R
T
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.
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"):
(1)
(2)
where:
A, B, C, D, A
1
, B
1
, C
1
and D
1
are constant values
depending on the material concerned; see table below.
R
ref
is the resistance value at a reference temperature (in
this event 25 C).
T is the temperature in K.
Formulae numbered (1) and (2) 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
.
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,
then:
or Z X + Y.
When:
TC = temperature coefficient
T = temperature deviation,
then:
The temperature tolerances are plotted in the graphs on the
previous page.
Example: at 0 C, assume X = 5%, Y = 0.89% and
TC = 5.08%/K (see Table ), then:
A NTC with a R
25
-value of 10 k has a value of 32.56 k
between -1.17 and +1.17 C.
