APPLICATIONS
Temperature measurement and control.
Bead thermistor with negative temperature coefficient, in a
glass envelope with two tinned durnet (CuNiFe) leads. The
device is non-flammable.
MARKING
The thermistors are marked with four colored 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.
