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.

PACKAGING

The smallest packing quantity is 500 units.
