MF72 Series 1.5D-15 Power NTC Thermistor 7A 1.5 Ohm 15mm Suitable For Switching Power SupplyMF72 Power NTC Thermistor Series
Small size, high power, strong ability to suppress surge current
Fast response
Material constant (B value) is large, and the residual resistance is small
Long life and high reliability
Complete series, wide application range
●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
◎Conversion 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
