Notes
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.
2. Valid for all types with the exception of 2322 640 5.474.
APPLICATIONS
• Temperature sensing and control.
These thermistors have a negative temperature coefficient.
The device consists of a chip with two tinned nickel leads and
is colour coded.
PACKAGING
The thermistors are packed in cardboard boxes; the smallest
packing quantity is 500 units.
MARKING
The thermistors are marked with coloured bands; see
Dimentions and “Electrical data and ordering information”
MOUNTING
By soldering in any position.
