Critical Technical Parameters of NTC Thermistor

This is a Negative Temperature Coefficient Resistor Whose resistance

changes with ambient temperature changes. Thermistor comprises 2 or 4

kinds of metal oxides of iron, nickel,cobalt, manganese and copper, being

shaped and Sintered at high temperature(1200℃ to 1500℃ )

* 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 eror.

* R25---Resistance Value at Rated Zero-power

The design resistance of the thermistor usually refers to the resistance value got at Zero-power at 25℃ , which is usually

indicated on the thermistor.

The maximum allowable continuous current passing through thermistor at 25℃.

* Dissipation Coefficient δ

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:δ = △P/ △T ,δ changes in response when the ambient temperature changes, within the

ranges of the working temperature.

Conversion power supply, switch power, UPS power, Kinds of electric heter, electronic energy-saving lamps, electronic ballast

etc all kinds of power cicuit proterction of electronic equipments, filament proterction of CRT, bulb and other lighting lamps.
