Aluminum electrolytic capacitors, such as the 500MXH470MEFCSN35X55 model, are the most commonly used type of electrolytic capacitor. They have a wide range of application fields and working principles.

Applications of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in many different applications, including audio equipment, electronic circuits, telecommunication systems, medical devices, and other consumer-based electronic products. In general, they are used in any application that requires a filter or decoupling capacitance due to their high capacitance, reliability, and low cost. They are also the most commonly used type of capacitor in AC applications because of their ability to store and release energy quickly at high electrical frequencies.

Additionally, aluminum electrolytic capacitors are popular in equipment that experiences transient loads or high ripple currents, including DC-DC converters, switching regulators, power supplies, inverters, automotive electronic systems, and microphone circuits. In some cases, their affordability also makes them the capacitor type of choice for PCB power filter capacitors.

Working Principles of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are constructed of two aluminum foils wound together, with the inner foil etched to create a large number of plates that increase capacitance. The plates are separated by an electrolyte, usually potassium hydroxide. The completed capacitor is then sealed in a non-conductive casing, where positive terminals are attached to one plate and negative terminals to the other.

Aluminum electrolytic capacitors operate using Faraday’s law of induction, where an electric field will arise between the two plates of a capacitor when a potential difference is applied between them. This electric field produces an electric charge that accumulates on each plate. When a dielectric material (electrolyte) is placed between the plates, it acts to increase the capacity of the field, thus increasing the capacitance.

Aluminum electrolytic capacitors also benefit from their ability to reduce impedance, or the opposition to the flow of energy in an electric circuit. This property makes them ideal for AC applications, as they can quickly surge and release energy during bursts of high frequency electrical signals. Aluminum electrolytic capacitors are also able to withstand high temperatures and high humidities, making them ideal for use in extreme environments.
