It is widely used in various fields such as communications, computer electronic circuit, power electronics, consumer electronics, industrial control and television. We can see that it is a device which can be widely used in society, and is an indispensable component in electronic production.In the communication field, EKXJ251ELL101ML20S are mainly used for the dissipation of surplus current in power systems, filters in digital circuits, as well as in electric oscillators circuits and pulse circuits. In the field of industrial control, aluminum electrolytic capacitors are used in dynamic switch circuits, as well as in sampling and holding circuits. They are also used in power electronic circuits, voltage dividers, and snubber circuits in power electronics fields, and for frequency tuning in computer electronic circuits. In the consumer electronics field, aluminum electrolytic capacitors can specifically be used for LCD TVs, DVD and other products as the filter capacitor.

2. Structure Characteristics of EKXJ251ELL101ML20S

EKXJ251ELL101ML20S aluminum electrolytic capacitor has the characteristics of small size, large capacity, long life and low cost. The polar aluminum electrolytic capacitor is a kind of electronic component with aluminum as an anode, a separator containing electrolyte as a dielectric, and a cathode being the conductive surface on the aluminum foil. The package size of the EKXJ251ELL101ML20S aluminum electrolytic capacitor is relatively small, and its height is only 10mm. Furthermore, low leakage current and high capacity can be achieved. The rated voltage is 2.5V and the products can provide different capacitance values of 0.1uf, 1uf, 10uf, 100uf, 1000uf and etc. The options are so wide that customers can choose according to their specific needs.

3. Working Principle of EKXJ251ELL101ML20S

Aluminum electrolytic capacitors are essentially different from ordinary capacitors in their working principle. The dielectric layer between cathode and anode in ordinary capacitor use ceramic, tantalum or waxed paper, while the dielectric layer of aluminum electrolytic capacitor is an anodized film formed on the surface of aluminum foil coated with an oxide film in a special electrolyte. The anodizing process causes a charge of electrons with opposite polarity at the cathode and anode surfaces. When the voltage is applied to the aluminum electrolytic capacitor, electrons at the aluminum layer move towards the positive electrode, resulting in the accumulation of negative charges on the aluminum layer, while positively charged ions in the electrolyte accumulate at the oxide layer of the aluminum surface layer. When a sufficient number of charges accumulate on both the anode and the cathode, the capacitor stores signal energy, and the current does not flow until the voltage exceeds a certain threshold limit.

Conclusion

EKXJ251ELL101ML20S aluminum electrolytic capacitor is an essential electronic component in many fields. In addition to its application field discussed in this article, it can also be used in many other applications, such as timing circuits, step-up and step-down converters, etc. Therefore, knowing the application field, structure characteristics and working principle of aluminum electrolytic capacitor is very helpful for people to better understand EKXJ251ELL101ML20S, and to make appropriate use of it in specific designs.
