Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, abbreviated as Al-el, are based on aluminum foil as the anode, a solid electrolyte as the cathode, and a semiconductor oxide film as the dielectric. They are one of the most commonly used types of capacitors thanks to their low cost, large capacitance and small size. The 517D227M200FV6AE3 is an example of a surface mounted aluminum electrolytic capacitor which is used in many different applications.

An aluminum electrolytic capacitor consists of an anode in the form of an aluminum foil, a cathode of a solid electrolyte, and an insulating layer of oxide formed on the surface of the aluminum foil. The oxide serves as the dielectric material and responsible for the capacitance of the capacitor. When voltage is applied, ions are drawn to the anode and stored within the dielectric layer, forming a conductive path between the two electrodes. This charge storage physical mechanism is often referred to as “double layer”, meaning a charge is stored both in the insulating layer and in the electrolyte solution. This results in a higher capacitance than regular capacitors.

The 517D227M200FV6AE3 aluminum electrolytic capacitor is a surface-mount device with a capacitance of 2200 μF and a rated voltage of 25 VDC. This model is typically used in a variety of applications, such as power supplies, voltage regulators, audio amplification and LED lighting. Especially, its excellent volumetric efficiency, low ESR and ESL has made it a popular choice for small form factor applications or high-density printed circuit boards. Furthermore, its high ripple current rating and long lifetime operations makes the aluminum electrolytic capacitor the ideal choice for high reliability applications such as those used in aerospace, automotive and medical industries.

The aluminum electrolytic capacitor is usually rated with a maximum working voltage, which is typically used as reference when selecting a capacitor. Operating voltage is the maximum working voltage rating of the capacitor multiplied by 0.90 for pulsing use, or doubled when made as a series connection. Exceeding the maximum rated voltage of the capacitor will cause dielectric breakdown and permanent damage.

In addition, the aluminum electrolytic capacitor is also rated with an endurance rating and a ripple current rating. The endurance rating expresses the number of hours that the capacitor can work at its rated voltage without any degradation. The ripple current rating indicates the amount of current that the capacitor can handle for a certain period of time without damage or significant performance reduction. The ripple current rating should be considered when selecting a capacitor for applications where the load is subject to changes or is exposed to large amounts of electrical noise.

In conclusion, aluminum electrolytic capacitors are widely used because of their low cost and high capacitance. The 517D227M200FV6AE3 is a specific type of Aluminum-el capacitor with high ripple current rating, low ESR and low impedance. It is commonly used in applications such as power supplies, voltage regulators, audio amplification and LED lighting. It is important to select the correct type and size of capacitor and take into consideration the minimum working voltage as well as the endurance and ripple current ratings.
