NTC Thermistor
Features
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℃
)
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 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.
* Max. steady state current.I
max
.
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.
Applications
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.
