Aluminum electrolytic capacitors are a type of capacitor that use aluminum foil as the anode, an electrolyte solution such as an acid as the dielectric, and a wire as the cathode. They are among the most popular capacitors and have numerous uses in the electronics industry. The MAL209753479E6 is one example of an aluminum electrolytic capacitor. This article will discuss the application fields and working principles of this capacitor.

Application Fields

The MAL209753479E6 is a high voltage aluminum electrolytic capacitor. It can withstand up to 450V of working voltage, making it ideal for use in power supplies, voltage converters, lighting ballasts, and other high voltage applications. It is also resistant to short circuit, making it suitable for motor starting applications. Its non-polarized design allows it to be used in AC voltage control circuits without issue.

Another key feature of the MAL209753479E6 is its long life span. It is designed to have a minimum life of 10,000 hours, making it suitable for use in long-term applications. Additionally, its temperature range (-55°C to +125°C) makes it suitable for various conditions, and its low ESR and ESL values make it ideal for snubber and filtering applications.

Working Principles

Underlying the high performance of the MAL209753479E6 is its simple, efficient design. The capacitor works by storing electrical energy through the action of electric fields and a thin dielectric layer on the aluminum foil. When a voltage is applied to the capacitor, the electric field causes electrons to be deposited on the anode and holes to be created on the cathode. This action establishes a net current between the two plates, allowing it to store energy.

The electrical energy stored in the MAL209753479E6 capacitor is released by gradually releasing the electrons from the anode and allowing them to fill the holes in the cathode. As the charge is released, the electric field dissipates and the voltage across the capacitor is reduced. This action makes the capacitor ideal for energy storage applications.

Conclusion

The MAL209753479E6 is a high performance, long life aluminum electrolytic capacitor. Its wide operating voltage, temperature range, and low ESR and ESL make it ideal for high voltage applications, motor starting, AC voltage control, and snubber and filtering applications. The capacitor works by storing electrical energy through the action of electric fields and its thin dielectric layer, and releasing the energy by releasing electrons from the anode.
