NTC Thermistors, Accuracy Line

FEATURES

• Accuracy over a wide temperature range

• High stability over a long life

• Excellent price/performance ratio

APPLICATIONS

• Temperature sensing and control

These thermistors have a negative temperature coefficient.

The device consists of a chip with two tinned solid

copper-plated leads. It is grey lacquered and colour coded,

but not insulated.
