NTC Thermistor

This is a Negative Temperature Coefficient Resistor whose resistance changes with ambient temperature changes. Thermistors comprise 2 or 4 kinds of metal oxides of iron, nickel, cobalt, manganese, and copper, being shaped and sintered at high temperature (1200C to 1500C).

Critical Technical Parameters of NTC Thermistor

Rt: Resistance Value at Zero-power
It's a resistance which is got at a fixed temperature on a basis of a testing power which causes resistance to vary in a range which can be ignored in relation to the total testing error.
R25: Resistance Value at Rated Zero-power
The design resistance of the thermistor usually refers to the resistance value got at zero-power at 25C, which is usually indicated on the thermistor.
Max. steady state current (Imax)
The maximum allowable continuous current passing through thermistor at 25C.
Dissipation Coefficient ()
It's the ratio of the changes with a thermistor dissipation power, in a pre-set ambient temperature, to the changes with the temperature. The formula is as below: = P / T. It changes in response when the ambient temperature changes, within the ranges of the working temperature.

Applications

Conversion power supply, switch power, UPS power, kinds of electric heter, electronic energy-saving lamps, electronic ballast etc. all kinds of power circuit protection of electronic equipments, filament protection of CRT, bulb and other lighting lamps.
