Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are one of the most common types of capacitors used in contemporary electronics. They consist of metal foil separated by a dielectric oxide film that has much higher capacitance than other types of capacitor technology, and their high capacitance makes them highly suitable for high-frequency and high-power applications. Housed in cylindrical cans containing two plates of aluminum foil, AECs are commonly used in power supplies, among other applications.

The B41821A8476M8 aluminum electrolytic capacitor is a radial, low-profile component that is designed to fit into tight spaces and draw less current for longer performance. It has a capacitance of 475uF and a voltage rating of 63V. This AEC is rated at 5,000 hours, which is higher than many other types of capacitors on the market.

Application Field

The low profile makes the B41821A8476M8 aluminum electrolytic capacitor ideal for any electronic device where space is an issue. It offers significant cooling effect in power supplies, amplifiers, and other high power applications, and its broad temperature range of -55°C to +85°C, make it suitable for harsh operating environments. It is often used in power supplies, frequency control, television receivers, automotive circuits, and other consumer electronics.

Working Principle

Aluminum electrolytic capacitors, such as the B41821A8476M8, use two plates of aluminum foil that are separated from each other by an insulating dielectric material, such as paper soaked in electrolytic solution or a mylar film. As current flows through the capacitor, the aluminum plates are charged with equal but opposite charges, creating an electric field in between the plates. This charge is what is stored in the capacitor, and is what is used to filter or pass current in electrical circuits.

The B41821A8476M8 uses special electrolytic solution to create a larger capacitance compared to other types of capacitors. Specifically, the 100% reel packing makes it easier to store for extended periods of time. In addition, the capacitor has enhanced voltage and temperature ratings to reduce power losses and provide longer life for the component.

Conclusion

The B41821A8476M8 aluminum electrolytic capacitor is an ideal component for tight spaces and high power applications. It is a radial, low-profile capacitor with a capacitance of 475uF and rated voltage of 63V and long service life of 5,000 hours. It is especially suited for power supplies, automotive, and other industrial and consumer applications, providing strong filtering and passing capabilities.
