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
