Synonyms
Thermally sensitive resistor
Definition
A thermally sensitive resistor, the primary function of which is to exhibit a change in electrical resistance with a change in body temperature (EIA Standard 1963).
Characteristics
Thermistors are metallic oxide electronic semiconductors which are manufactured from oxides of nickel, manganese, iron, cobalt, magnesium, titanium, and other metals. All are epoxy encapsulated with two leads. The first reported thermistor was attributed to the British physicist Michael Faraday in 1832, based on his study on the semiconducting behavior of silver arsenide (Ag2S) (Faraday 1832).
The relationship between the resistance of a thermistor and its body temperature may be expressed as
where β is the “material constant” of the thermistor, R(T) is the resistance at temperature T under self-heated conditions, and R0(T0) denotes the resistance at T0with...
