DESCRIPTION
These thermistors have a negative temperature coefficient.
The part consists of a NTC chip, soldered between two tin
plated copper wires. It has a gray base coating and is color
band coded. The coating has no specified insulation
properties.
PACKAGING
The thermistors are packed in bulk or tape on reel; see part
numbers and relevant packaging quantities.

MARKING
The thermistors are marked with colored bands; see
dimensions drawing and “Electrical data and ordering
information”.
MOUNTING
By soldering in any position.
Not intended for potted applications.

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.
Vishay BCcomponents
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,
