Super capacitance, also known as electrochemical capacitance, double layer capacitor, gold capacitor, Fara capacitor, is an electrochemical element developed in the 1970s and 1980s to store energy through polarized electrolytes.
It is different from the traditional chemical power supply. It is a kind of power supply with special performance between traditional capacitors and batteries. It mainly relies on double layers and redox pseudocapacitive charge to store energy.

(3) High current discharge capacity is very strong, energy conversion efficiency is high, process loss is small, energy circulation efficiency of large current is greater than or equal to 90%.
(4) High power density, up to 300W/KG~5000W/KG, equivalent to 5~10 times of batteries
(5) The raw material composition, production, use, storage and disassembly of the product are not polluted and are ideal green power sources for environmental protection.
(6) The charging and discharging circuit is simple, does not need the charging circuit like rechargeable battery, has high safety factor, and is maintenance-free for long-term use.
(7) Good ultra-low temperature characteristics, wide temperature range from -40 to + 70 degrees C

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 thermistors 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.

Radial Leaded Ultra Big Power NTC Thermistor MF73 For Switching Power Supply I Description Of The Ultra Big Power NTC Thermistor MF73 High-Power NTC Thermistors are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current. Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment. II Application Of The Ultra Big Power NTC Thermistor MF73 * All kinds of power supply,UPS power supply,Switching power supply * EV charger,charging pile * Motor driver,superpower server motor driver,logic controller * High power plasma electric welder,cutting machine,super power lightning lamp * Nuclear managetic resonance equipment,super power audio power amplifier,high circle transformer * The solar panel arrays with high capacity power inverter * The industrial robot drived by high voltage power supply, intelligent electric cabinet with low voltage.
