Aluminum electrolytic capacitors are the most commonly used capacitors in electronic products. They are widely used in various consumer electronic products, such as radios, computers, televisions, mobile phones and battery-powered electric tools. EMZF350ADA220MF73G is one type of popular aluminum electrolytic capacitors. This article will discuss in detail its application fields and working principle.

Application fields

EMZF350ADA220MF73G is a miniature radial aluminum electrolytic capacitor with long life. It has a capacitance of 350µF and rated voltage of 25VDC, which makes it widely used in filters, decoupling and bypass of electronic circuits in electronic products. In addition, this kind of capacitor also has the function of buffering, smoothing, preventing pulse input interference (such as, in computer power supplies and LCD backlights), and slowing the speed of waveform change. Therefore, it is widely used in various computer electronic equipment, energy-saving lamps, digital equipments, LCD equipments, light box backlight, etc.

Working Principle

The working principle of EMZF350ADA220MF73G mainly depends on the physical behaviors of liquid and solid materials. Its main body is composed of an electrolyte and two electrodes, which are the negative and positive terminals of the capacitor. In addition, the two electrodes are separated by an insulator (called "dielectric"). During operation, electrons will flow from the negative electrode to the positive one due to the applied voltage, and then be stored in the dielectric. When the applied voltage is removed, the stored charge will be quickly discharged, which is essentially capacitance effect.

Due to the polarization effect of liquid electrolyte and a very thin barrier layer at the interface between solid and liquid, aluminum electrolytic capacitors exhibit excellent performance in terms of stability and endurance ability. With EMZF350ADA220MF73G, electric energy can be quickly stored and released and consumed by the devices in use. During operation, the unique characteristics of aluminum electrolytic capacitors contributes to a more smooth circulation of electric power and it also minimizes the system failure caused by overvoltage and over-current.

Conclusion

EMZF350ADA220MF73G belongs to the aluminum electrolytic capacitor family. Its capacitance and rated voltage make it a versatile electronic component which can be used in a wide range of applications. Its working principle mainly depends on the physical behaviors of liquid and solid materials, with electric energy stored and released through special effects of liquid electrolyte and the interface between solid and liquid. Such a component not only can provide a smooth electric power to the devices, but also can reduce failure rate caused by overvoltage or over-current.
