Specifications
MF72 Power NTC Thermistor series
Introduction
When you turn on An electrical equipment, the surge current can be restrained by a power NTC termistor 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't affect normal operating Current. Therefore, using power NTC thermistor is a most effectively and most brief measure to restrain surge current, protecting electrical Equipment from destruction.
Applications
Coversion power-supply, switch power-supply, UPS power-supply
Electronic energy saving lamps, electronic ballast and all kinds of electric heater
All kinds of RT, display
Bulb and other lighting lamps
Characteristics
Small size, strong power and strong capability of surge current protection.
Fast response to surge current
Big material constant (B value), Small remain resistance
Longevity of service. High reliability
Integral series, extensive operating range
