QUICK REFERENCE DATA
Note
1. Response time in silicone oil MS200/50. This is the time needed
for the sensor to reach 63.2% of the total temperature difference
when subjected to a temperature change from 25
°
C in air to
85
°
C in oil.

MARKING
The thermistors are marked with four coloured dots on the
glass envelope; see Component Outline drawing and
Electrical Data and Ordering Information table.
MOUNTING
By soldering in any position.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packaging quantity is 100 units.
FEATURES
•
Small diameter
•
Quick response to changes in temperature
•
Very high long term stability
•

•
Resistant to agressive environments
APPLICATIONS
Temperature measurement.
Bead thermistor with negative temperature coefficient, in a
glass envelope with two tinned durnet (CuNiFe) wires. The
device is non-flammable.
