Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are a type of capacitor commonly used in electronic circuits. AECs consist of two aluminum foil strips stacked together, separated by an electrolyte (an acidic solution). They are often referred to as “wet” capacitors because they require periodic servicing or “binning” to maintain their efficiency. This type of capacitor can store a large amount of electric charge (similar to a battery) and provide a much higher capacitance than standard solid-state capacitors. AECs have become the most common type of capacitor used in electronic circuits, due to their high capacitance, long life, and stability.

383LX681M450B052V application field and working principle

The 383LX681M450B052V is a type Of Aluminum Electrolytic Capacitor. It is widely used in the Telecommunications, Lighting, Computing, Consumer Electronics and Automotive industries, and is the most common type of capacitor used in these industries. This type of aluminum electrolytic capacitor has a capacitance range of 681uF, a voltage rating of 450V, a temperature range of - 55 to +85°C and an extended service life of up to 10,000 hours depending on operating conditions.

The working principle of the 383LX681M450B052V is the same as other aluminum electrolytic capacitor .it consists of two aluminum foil sheets, separated by an electrolyte. The electrolyte is usually a mixture of organic solvent and water and contains a variety of ions. When the voltage is applied, the positive ions of the electrolyte are attracted to the negative-charged aluminum foil, forming a conductive layer between the two aluminum foils, and the capacitance increases. When no current flows, the ions are repelled from the negative side of the aluminum foil, forming an insulating layer between the two aluminum foils, and the capacitance decreases.

In nature, the aluminum foil anode should be forming a layer of oxide layer to ensure the insulation of the capacitor, which is the key factor of aluminum electrolytic capacitors. When the voltage is beyond the peak value, the oxide layer will be broken down and the current will increase, thus making the capacitor other components will fail, so the withstand voltage must be kept. Before using, it is also important to check to ensure that the stress voltage is greater than the expected operating voltage.

In summary, 383LX681M450B052V is an Aluminum Electrolytic Capacitor, widely used in Telecommunications, Lighting, Computing, Consumer Electronics and Automotive industries, it has a capacitance range of 681uF, a voltage rating of 450V, a temperature range of - 55 to +85°C and an extended service life of up to 10,000 hours. Its working principle is the same as other aluminum electrolytic capacitor, it consists of two aluminum foil sheets, separated by an electrolyte, and the oxide layer should be formed before using to ensure capacitor working properly.
