Application Field

Aluminum electrolytic capacitors can be found in a wide variety of applications. Some of the common applications include supplying energy in electrical circuits, filtering noise in audio systems, providing timing in digital circuits, and regulating voltage in power supply units. Due to their high capacitance values, these capacitors are generally used in circuits that require a high amount of energy, such as high-power inverters, DC-DC converters, and automotive starting systems.

Working Principle

Aluminum electrolytic capacitors work by storing electrical charge in an electrolytic membrane. This membrane is made up of a combination of aluminum foil as the anode, a non-conductive electrolyte, and a porous insulator. When positive voltage is applied to the anode aluminum foil, a double electric layer is formed on the surface of the aluminum foil. This layer of charge is then separated by the thin electrolyte layer, resulting in a capacitance effect.

The capacitance of an aluminum electrolytic capacitor is determined by its internal structure. Generally speaking, larger capacitors will offer higher capacitance values, and smaller ones will provide lower capacitance values. The capacitance is also affected by the electrolyte material used inside the capacitor, as well as the temperature of the environment. As such, these capacitors are commonly used in applications where reliable capacitance, stability, and temperature range are necessary.

In summary, the B43508E2277M82 is an aluminum electrolytic capacitor which can be widely used in a variety of applications. It is a reliable choice for those seeking a high-performance capacitor due to its high capacitance value, rugged construction, long life, and good overall performance.
