Thermistors are temperature-sensing elements made of semiconductor material that has been sintered in order to display large changes in resistance in proportion to small changes in temperature.
This resistance can be measured by using a small and measured direct current, or dc, passed through the thermistor in order to measure the voltage drop produced. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K.

Suitable for different application, from automotive to industrial and vending.

NTC Thermistors

NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases.
