Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an example of an electrochemical capacitor, which consists of two metal plates immersed in an electrolyte. The capacitor has two aluminum plates separated by that electrolyte. The electrolyte is an ionic conductive liquid or gel, which, in this case, is usually an acidic solution. This electrolyte is the working principle behind these capacitors.

Every aluminum electrolytic capacitor is marked with its standard values such as 25YK1000MEFC10X20. The first two figures (25) refer to the height of the can (in millimeters). The second two digits represent the diameter of the can (in millimeters). The letter is the code used to designate the type of capacitor, with Y meaning the electrolyte is oil-filled and K meaning it is in the form of a tube. The last three digits indicate the capacitance value of the capacitor (in Farads). The two letters in the code (M and F) stand for the design used to construct the capacitor – the M stands for Multi-layer and the F for Radial. Finally, the following two digits represent the maximum working voltage of the capacitor (in volts).

Aluminum electrolytic capacitors are used in a number of different electronic circuits and applications. In general, they are used to store charge for short periods of time, in order to deliver a brief burst of current upon demand. They are commonly used as part of computer power supplies, audio equipment, video equipment, and other applications where quick bursts of power are needed. They are also often used in high-frequency applications, such as in the oscillators found in cell phones.

Given their robust design and wide range of applications, it can be seen why aluminum electrolytic capacitors are such a popular choice in a number of electronic circuits. In addition, their high capacitance values and long life make them the ideal choice for applications requiring a large amount of charge storage, such as power supplies.

Finally, aluminum electrolytic capacitors are relatively cheap and easy to manufacture, which helps keep costs down for customers. This makes them an excellent choice for high-volume or low-cost applications.
