Vishay BCcomponents
NTC Thermistors, Molded Range
FEATURES
•
Excellent for surface temperature measurement
•
Designed for harsh environments
•
Based on the
“2322 640 0....”
naked thermistor chips.
APPLICATIONS
•
Temperature control.
These thermistors have a negative temperature coefficient.
The device consists of a molded chip with two tin-plated solid
nickel leads. The body color is white and the device is
non-flammable.
