Negative temperature coefficient Power NTC thermistor for Conversion power-supply
Power Resistor MF72 NTC Thermistor Black NTC 3d-15
General Introduction
When you turn 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, so the consumed power can be ignored.Therefore, using power NTC thermistor
is a most effectively and most brief measure to restrain surge current,protecting electrical
equipment from destruction.
Application:
1.Conversion power-supply, switch power, ups power.
2.Electronic energy saving lamps, electronic ballast and all kinds of electric heater.
3.All kinds of RT, display.
4.Bulb and other lighting lamps.
Feature
1.Small size, strong power and strong capability of surge current protection.
2.Fast response to surge current.
3.Big material constant (B value), Small remain resistance.
4.Longevity of service, High reliability.
5. Integral series, extensive operating range.
