Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most common type of capacitor. They are composed of an anode and cathode separated by an electrolyte. These capacitors can be found in a variety of applications and form factors, from small ceramic devices to large electrolytic tanks. The 400RX304.7MTA8X20 is an aluminum electrolytic capacitor which features a rated voltage of 400V, a capacitance of 47µF, and an operating temperature range of -25°C to +85°C.

Application Field

Aluminum electrolytic capacitors can be used in a wide range of applications, from automotive to consumer electronics. In automotive applications, aluminum electrolytic capacitors are commonly used to filter out unwanted noise in audio systems and to reduce the effects of alternator ripple in electrical systems. Aluminum electrolytic capacitors are also used in power supplies for computer and television circuits, as well as for motor drives and energy storage. In the consumer electronics industry, aluminum electrolytic capacitors are used for filtering and buffering, to ensure that the power used by any device is regulated and free of noise. They are commonly found in electronic devices such as TVs, radios, microwaves, and DVD players. Aluminum electrolytic capacitors are also used to filter power supplies in LED lighting and LCD displays.

Working Principle

The basic principle of aluminum electrolytic capacitors is based on the dielectric properties of a thin oxide layer which forms on the surface of the aluminum. The aluminum foil, which serves as one of the electrodes of the capacitor, is typically etched in a particular pattern to achieve a higher capacitance. The other electrode is the electrolytic solution, which is made up of various chemicals. When a voltage is applied across the two electrodes, the oxide layer is formed on the surface of the aluminum foil, creating a capacitor. This oxide layer acts as a dielectric, and the capacitance of the capacitor is determined by the thickness and area of the oxide layer. In order to maintain long-term stability, aluminum electrolytic capacitors are designed with a variety of features such as overload protection, thermal protection, and vent filters. When the capacitance of the capacitor reduces due to aging, an additional layer of oxide is formed on the surface of the aluminum foil, restoring the capacitance to its original value.

Conclusion

Aluminum electrolytic capacitors are versatile components that can be used in a wide range of applications. From automotive systems to audio and power supplies, they provide reliable filtering and buffering and offer excellent performance in a variety of conditions. The 400RX304.7MTA8X20 is an aluminum electrolytic capacitor which offers a rated voltage of 400V, a capacitance of 47µF, and an operating temperature range of -25°C to +85°C. It is an ideal choice for a wide range of applications.
