Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that uses aluminum foil and an electrolyte to store electric charge. This type of capacitor is often used in electronic circuits that need large capacitance at high voltage or temperature extremes. The capacitance of an aluminum electrolytic capacitor is determined by the size of the aluminum foil, its thickness, the distance between the two foils, and the nature of the electrolyte.

The aluminum electrolytic capacitor 10ML470MEFCTA8X9 is designed for use in low ripple applications and features a low temperature coefficient. The capacitor is designed to withstand higher voltages than standard capacitors and has a longer service life than other capacitor types. The device is commonly used in signal and power inductive circuits and is known for its excellent insulation properties.

Application Field and Working Principle

Aluminum electrolytic capacitors have a wide variety of applications in the electronics industry. One of the most common uses is in combination with integrated circuits, and these capacitors can be used to provide decoupling, filtering, or storage of power or signal. They are also used for power supply purposes, such as smoothing, bypassing, and filtering.

The working principle of an aluminum electrolytic capacitor is quite simple. It consists of two aluminum foils coated with an electrolyte. A thin dielectric oxide film forms between the two foils when a voltage is applied. As this oxide film develops, it stores electrical energy and acts as a capacitor. The capacitance of the capacitor is proportional to the surface area of the two foils and the thickness of the oxide film.

Aluminum electrolytic capacitors are widely used in audio-frequency circuits due to their low dissipation factor and low equivalent series resistance. They are also ideal for applications where high ripple current is present or where high capacitance is needed. Common examples include power supplies, filters, and signal conditioning circuits. They are also used in motor controls and other power electronics and in RF circuits.

The 10ML470MEFCTA8X9 aluminum electrolytic capacitor is designed to operate in tough conditions, including applications with high temperature and vibration. The device can also handle higher wattages than other types of capacitors and provides increased safety in many applications. The low ESR and ESR characteristics of the capacitor provide excellent ripple current handling capability.

Aluminum electrolytic capacitors such as the 10ML470MEFCTA8X9 are essential components in many electronic circuits and are known for providing accurate, low-loss power conditioning. Their low cost, long life, and ability to handle extreme temperatures and voltage make them well suited for a variety of applications.
