Disc NTC Thermistor 2.5D-15 2.5 Ohm 15mm 7A Negative Temperature Coefficient Pitch 7.5mm
Production Introduction
The MF72 power NTC thermistor is a kind of semiconductor ceramic element that mostly made from transition metal oxide material, and belongs to negative temperature thermistors. When you tune on an electrical equipment ,the surge current can be restrained by a power NTC thermistor connected in series with the power circuit .Because of the continuing action of current, temperature of power NTC thermistor raising, the resistance will rapidly drop to a small value, the consumed power can be ignored. So it can not affect normal operating current. Therefore, using power NTC thermistor is a most effectively amd most brief measure to restrain surge current, protecting electrical equipment from destruction.
APPLICATION
Convension power supply , switch power , kinds of electric heater , electronic energy-saving lamps , electronic ballast etc . All kinds of power circuit protection of electronic equipments , filament protection of all kinds of RT , display , bulb and other lighting lamps .
