Aluminum electrolytic capacitors are a type of capacitor in electrical and electronic components that predominantly use an aluminum oxide plate with two aluminum foils on either side as the capacitance element. This type of capacitor generally provides a larger capacitance with a smaller size than other types of capacitors. They are used extensively in electronic circuits such as amplifiers and filters to store electrical energy and filter signals, and can also be used as a coupling capacitor in power supplies. This article will discuss the 226SVL050MEL, a type of aluminum electrolytic capacitor, and its application fields and working principle.

The 226SVL050MEL is an aluminum electrolytic capacitor with a rated capacitance of 50μF, rated voltage of 50V, and rated ripple current of 470mA. It is an enclosed type capacitor which has two pin-terminals and allows an operating temperature range of -55℃ to +105℃. Its size is 22mm in diameter and 26.5mm in height, yet it has a large capacitance due to its use of an aluminum anode with an oxide layer and two aluminum foils separated by an electrolyte on either side as the capacitance element. This type of capacitor is used in analog circuits, such as op amps, and for power supplies in TVs and audio systems, as well as for voltage stabilization, as it has a large capacitance and a high rated voltage.

The working principle of an aluminum electrolytic capacitor is based on the fact that charged ions can move from one aluminum surface to the other while passing through the separator and the electrolyte. When the capacitor is connected to a power supply, electrons from the negative terminal are attracted to the anode, causing a positive charge to accumulate on it. As the voltage increases, the electrons on the cathode are repelled by the positive charge on the anode, thus creating a strong electric field across the separator. This electric field draws the cations of the electrolyte towards the anode, while the anions are repelled and drawn towards the cathode. This creates an accumulation of charges on the surface of the anode, thus providing the capacitance.

In summary, the 226SVL050MEL is an aluminum electrolytic capacitor that is used in analog circuits, power supplies, and voltage stabilization due to its large capacitance and high rated voltage. Its working principle is based on the attraction and repulsion of cations and anions under an electric field, leading to the accumulation of charges on the anode surface and providing the capacitance. This makes it a great choice for many applications where a large capacitance is needed in a small size.
