Aluminum electrolytic capacitors, also known as electrolytic capacitors, are types of capacitors that use an aluminum foil with an etched surface, usually covered with an oxide film as one of its electrodes. The other electrode is created by connecting an anode material to the etched foil. The resulting assembly is then immersed in an electrolyte solution, such as ethylene glycol, to create the capacitor. Aluminum electrolytic capacitors can be used in a wide variety of applications, from filtering to storing voltage, to providing a snubber in power supply or pulse networks. Despite their many uses, they have some drawbacks such as their limited lifespan and need for high temperatures to become effective.

The B43540A2228M82 is an aluminum electrolytic capacitor. It is part of the B2 series and is rated for a rated temperature of 85°C, with a rated capacitance of 220μF, and a rated voltage of 400V. It has a can size of 8 x 11mm. It is nickel-plated, with a metal end seal.

The B43540A2228M82 is commonly used in power supplies, snubbers, audio filters, and in noise suppression in switching power supplies. It is also used in signal filtering, where it can filter out low-frequency ripple and high-frequency noise from power sources. It is also useful for smoothing out pulses in high-frequency, high-voltage circuits where it can provide a local energy reserve.

The working principle of the B43540A2228M82 aluminum electrolytic capacitor is based on its ability to store charge. As electrons move through the conductive plates, they create an electric field between the plates. This electric field then repels and attracts the electrons, thus creating a capacitance or store of electric energy that can be used later. The oxide film on one of the plates acts as an insulator, preventing current from flowing through the capacitor. When the voltage is removed, the oxide film breaks down and reforms, allowing current to flow through the capacitor and charge it again.

The B43540A2228M82 is a reliable and cost-effective aluminum electrolytic capacitor. Its applications include use in power supplies, snubbers, audio filters, and noise suppression in switching power supplies. It is also useful in signal filtering, smoothing out pulses in high-frequency, high-voltage circuits, and providing a local energy reserve. The working principle of the B43540A2228M82 is based on its ability to store charge through the electrostatic field created by the conductive plates and oxide film.
