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