Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are one of the most commonly used passive electrical components. They are mainly used for power supply decoupling, energy storage and frequency compensation of electronic circuits. This article will discuss the specific application field and working principle of EGXF250ELL511MJC5S aluminum electrolytic capacitor.

Application Field

The most common application of EGXF250ELL511MJC5S aluminum electrolytic capacitor is for power supply decoupling. It is one of the common ways of breaking the direct current between power supply and load, so as to ensure that the load circuit works stably. At the same time, electromagnetic noise generated by power supply can be improved. Moreover, in DC/DC converters (such as switching power supplies, etc.), AC bypass capacitors will limit the current ripple of output power, divide the high frequency noise from power supply into the ground. In addition, due to its high capacitance, EGXF250ELL511MJC5S aluminum electrolytic capacitor is also used to store energy in switching power supply.

Working Principle

As a kind of capacitor, the EGFX250ELL511MJC5S aluminum electrolytic capacitor also adopts the principle of electrostatic capacitance to work. Its basic structure is composed of metal can, electrolytic paper, insulating coating, seal, gasket, cathode plate, anode pole and tin-plated terminal. The cathode plate is a dielectric oxide film formed on the surface of anode pole by electrolysis. Insulation coating and adhesive are respectively coated between dielectric oxide film and anode pole and seal.A pair of electrolytic papers are inserted into the anode pole and cathode plate, in which electrolyte liquid is filled, and two terminals in the can are connected to the anode and cathode poles. When the AC power supply voltage is applied to the two poles of the capacitor, an electric field will be generated in the oxide film. This field attracts and captures a variety of positive or negative ions between the oxide film and the electrolyte liquid. A layer of oxide film is arranged in between, and an electric field is formed between two levels of ions, forming a capacitor. Therefore, thin oxide film is the core of EGXF250ELL511MJC5S capacitor.

Conclusion

In conclusion, EGXF250ELL511MJC5S aluminum electrolytic capacitor has a wide range of applications, mainly for power supply decoupling, energy storage and frequency compensation of electronic circuits. It works on the principle of electrostatic capacitance and its basic structure consists of metal can, electrolytic paper, insulation coating, seal, gasket, cathode plate, anode pole and tin-plated terminal.
