Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have found wide use in many applications like power supply, power filtering, pulsed load, RF filtering and energy storage. The 50YXG180MEFCTA8X20 aluminum electrolytic capacitor is one such type widely adopted in different applications, owing to its features like a high-polarity rating of 63V to 200V, a minimum capacitance value of 180 µF to 2000 µF, and a wide temperature range of -25°C to +85°C. This article has been developed to explain what the aluminum electrolytic capacitor is, its different application fields and working principles.

What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is a type of electrochemical capacitor with a cathode that is made of aluminum foil with an oxide layer that acts as the dielectric. It consists of two aluminum layers, an electrolyte, and two current-carrying electrodes. It also features a non-solid electrolyte which allows for higher capacitance values as compared to other capacitor types. The aluminum electrolytic capacitors have low impedance values with little change in the impedance even at high frequencies. It also features a small leakage current, making it a good choice for application fields where leakage current is an issue.

Application Fields

Aluminum electrolytic capacitors are widely used in many different applications, such as power supply, power filtering, pulsed load, RF filtering, and energy storage. Power supply applications make use of the high current capacity of the aluminum electrolytic capacitor to provide surge protection and filtering, which helps to improve the reliability of the power supply. It can also be used in pulsed load applications to provide an effective way of power smoothing and AC line filtering. In RF filtering applications, aluminum electrolytic capacitors are used to reduce noise by providing effective shielding and low losses. Finally, aluminum electrolytic capacitors are also used in energy storage applications, where they offer a low cost and reliable solution.

Working Principle

The working principle of aluminum electrolytic capacitors involves the storage of energy in the form of electrical charges. When a voltage is applied across the plate, electrons are attracted to the aluminum surface and become deposited on the oxide layer, causing a capacitance to form. This capacitance can store electrical charges until the capacitor is discharged. When the capacitor is discharged, the accumulated electrical energy is released, and the capacitor is ready to charge again. The amount of charge stored in the capacitor depends on the voltage applied across it and also on the capacitance of the capacitor.

Conclusion

The 50YXG180MEFCTA8X20 aluminum electrolytic capacitor is a versatile type of capacitor that is used in a variety of applications due to its high-polarity rating, wide temperature range, and large capacitance values. Its low impedance values provide effective filtering and shielding capabilities, which are beneficial in power supply, pulsed load, RF filtering, and energy storage applications. Its working principle involves the accumulation and release of electrical charge, which allows the capacitor to store and efficiently discharge electrical energy for different applications.
