Quality Thermistors and Probes

A thermistor, or thermally sensitive resistor, is a resistor which changes resistance in response to a change in temperature. There are two basic types
of thermistors, NTC or Negative Temperature Coefficient and PTC or Positive Temperature Coefficient thermistors. NTC thermistors exhibit a decrease
in resistance when temperature rises. PTC thermistors exhibit an increase in resistance when temperature rises. QTI manufacturers both PTC and
NTC thermistors in a broad selection of package styles and resistance values.

	Negative Temperature Coefficient (NTC) Thermistors Negative Temperature Coefficient (NTC) thermistors exhibit decreasing electrical resistance with increases in environmental temperature and increasing electrical resistance with decreasing temperature.
	Positive Temperature Coefficient (PTC) Thermistors Positive Temperature Coefficient (PTC) thermistors exhibit increasing electrical resistance with increases in environmental temperature and decreasing electrical resistance with decreasing temperature.
	NTC Thermistor Probes Thermistor probes can be produced in many combinations or thermistor elements, probe housing, lead configuration and connector for applications where a surface, air or liquid temperature sensor probe is required. Click on the headings above to view current ranges
