What is a Thermistor?

Get the answer from our well-experienced professionals.

NTC thermistor is a thermally sensitive element composed of semiconductive fine ceramics.
The name thermistor comes from “a thermally sensitive resistor”, and its resistance drastically changes with temperature . The resistance of ordinary materials rises slightly as temperature rises, whereas NTC (negative temperature coefficient) thermistors exhibit a sharp decrease in resistace. Thermsitors manufactured and supplied by Nanjing Shiheng are all NTC thermistors.

The following descriptions are appliance only to NTC thermistors.

Thermsitors are made from transition metal oxides, primarily of Mn, Ni and Co, sintered into a fine ceramic body.

Shiheng’s thermistors cover a wide range of temperatures from -50 to 500 ℃ that is required for daily temperature control.  Our compact, stable and highly sensitive thermistors are used in large quantities as temperature sensors and for temperature compensation in many fileds such as home appliances and industrial equipment.
