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.

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. II Features Of The SMD NTC Thermistor 0402 1. Excellent solderability and high stability in environment 2. Excellent long time aging stability 3. High accuracy in resistance and B-constant 4. Reflow soldering possible 5. Lead is not contained in the product. 6.

Taped In Reel High Accuracy 0805 Monolithic Multilayer NTC Thermistor 100K 5% 4250 I Description Of The Multilayer NTC Thermistor 0805 Standard Surface Mount NTC Thermistor available in the 0805 package. NTC (Negative Temperature Coefficient) thermistors, which are typically composed of metal oxides, are manufactured to take on the form of disks, rods, chips and other shapes. A more common shape, the SMD (surface mount device), is widely used in standard reflow soldering processes. The different values and tolerances offered by the industry allow many renditions of package sizes within the dimensional constraints of an EIA standard. Although the SMD EIA standard specifies a maximum component height, in most cases a minimum is not, allowing the manufacturer greater flexibility in offering different values within an NTC. This bulletin will focus on the methods and materials recommended for component attachment either through hand soldering for prototype construction or reflow/wave soldering operations for normal production.
