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: The resistance obtained at a fixed temperature based on a testing power that causes resistance to vary within a range that 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 obtained at zero-power at 25C, which is usually indicated on the thermistor.
Max. steady state current (Imax): The maximum allowable continuous current passing through the thermistor at 25C.
Dissipation Coefficient (): The ratio of the changes in thermistor dissipation power, in a pre-set ambient temperature, to the changes in 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.
