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.

1005 Metric SMD NTC Thermistor 0402 10kOhms 1% 3380K For Battery Chargers I Description Of The SMD NTC Thermistor 0402 NTC thermistor is a ceramic semiconductor thermal crystal sintered from various metal oxides mainly manganese, cobalt and nickel. It is extremely sensitive to temperature changes. Its zero-power resistance varies with the body temperature. As the temperature increases, the resistance value decreases exponentially, and the temperature coefficient is as high as (3~6%/â). A small temperature change will cause a large resistance value change. According to the R-T resistance temperature curve of the thermistor, the precise resistance value of each temperature point can be measured. In the circuit, the temperature can be digitally corresponded through the resistance value for temperature measurement and control.AMPFORT thermistors have low thermal time constants which result in extremely high rates of resistance change to accurately track the temperature.
