Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors or AECs represent a popular class of capacitors that are used in most electrical appliances, including computers, TV sets, mobile phones, and other household or industrial appliances. AECs possess the highest capacitance and volumetric capacitance density among comparable capacitors, allowing for their use in limited space applications.Also known as tantalum capacitors, AECs are constructed of a piece of aluminum foil that is patterned with a series of cylindrical cavities, each of which contains an electrolytic gel. An anode is placed in the cavities to provide an ionic charge. AECs are polarity-sensitive and have low leakage currents, which makes them ideal for power filter applications.

B41456B7479M000 Application Field

B41456B7479M000 aluminum electrolytic capacitors are often used in electrical devices such as TVs, computers, cell phones, and other appliances. It is a multi-anode type product with higher capacitance values than the normal single-anode products. It is suitable for high-frequency applications and usually used as a filter in power supply circuits.

Working Principle of B41456B7479M000

The working principle of B41456B7479M000 aluminum electrolytic capacitors is based on the Faraday principle. When a voltage is applied across the two terminals of the electrolytic capacitor, an electric field is created between the anode and the cathode, and an electrolytic liquid is formed at the cathode. The ions from the electrolyte pass through the electroplated barrier and deposit onto the anode to form the capacitor plates. The electric field between the two dielectrics causes the capacitance of the electrolytic capacitor to increase in proportion to the applied voltage. The high capacitance value and volumetric capacitance density makes it ideal for applications with limited space.

Advantages of B41456B7479M000

B41456B7479M000 aluminum electrolytic capacitors offer some advantages over other capacitor types, including:

• High capacitance and volumetric capacitance density
• Low leakage current
• High temperature stability
• High surge current capability
• High-frequency performance
• Low equivalent series resistance

Another advantage of AECs is their low cost and ease of installation. AECs are also extremely versatile and can be used in a wide range of applications.

Conclusion

B41456B7479M000 aluminum electrolytic capacitors are unique and versatile types of capacitors that are widely used in many electrical devices. With its high capacitance and volumetric capacitance density, low leakage current, high temperature stability, high frequency performance, and low equivalent series resistance, it is an ideal choice for a variety of applications.
