    MF75 Super Power NTC Thermistor For Audio Power Amplifier Inrush Current Protection


    I Description Of The MF75 Super Power NTC Thermistor


    Inrush current is the momentary surge of current created when power is turned on to motors,transformers,power suppliers and heating elements. The more power required by industrial equipment,the larger the inrush current. It can effectively quench the inrush current by means of in series with power NTC thermistor in return circuit of power supply. The thermistor’s resistance decreases dramatically following the inrush,allowing the steady state curent to flow with very little resistance.This effect provides inrush current protection, yet allows efficiency during normal operation.The power NTC Thermistor produced by Dongguan Ampfort Electronics Co.,Ltd. with large scale,especially MF73T,MF73,MF74,MF75 serial products with big size,which can be applied in such inrush protection with industrial level as industrial robots and automation.


    II Application Of The MF75 Super Power NTC Thermistor


    > Nuclear magnetic resonance equipment
    > Super power audio power amplifier
    > High power circle transformer
    > The solar panel arrays with high capacity power inverter
    > The industrial robot drived by high voltage power supply
