NTC8D-7

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.Imax. 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.
