How Does an NTC Thermistor Work??
NTC thermistors are electronic devices whose
electrical resistance varies in inverse proportion to
environmental temperature.
Types Of NTC Thermistor
The resistance of an NTC thermistor decreases as the temperature rises, and vice
versa.
Construction
An NTC thermistor is typically a semiconductor, made from oxides of
cobalt, copper, nickel, iron or titanium, pressed into a small bead, disk or
wafer.
An NTC thermistor initially has a high resistance, which limits the
current that can flow.
Operation
Zero-Power Resistance
An NTC thermistor has what is known as a zero-power resistance. This is its resistance when power dissipation as heat is negligible.
