16JKV47M6.3X5.5

Aluminum electrolytic capacitors are a type of electrical capacitor that has the remarkable capability of storing a significant amount of charge relative to its size. The 16JKV47M6.3X5.5 aluminum electrolytic capacitors are widely used for their ability to maintain a higher capacitance than other types of capacitors in the same space and for their highly reliable performance in extreme temperature environments.

The 16JKV47M6.3X5.5 aluminum electrolytic capacitor is a radial leaded, mid-range capacitance device with a floating radial leaded rechargeable option. The capacitor is made with an anode aluminum foil, which is the positive electrode, and a dielectric of manganese dioxide. A cathode foil, which is the negative electrode, is also incorporated into the capacitor along with an insulating paper between them and the steel cover.

Application Field and Working Principle

Aluminum electrolytic capacitors are suitable for DC filtering and bypassing applications. They are commonly used in circuits where space, price, and the capacity to withstand high temperatures is important. The capacitors are also used for power supply filtering, audio equipment filtering, and various signal bypassing applications.

The working principle of the aluminum electrolytic capacitor is based on the principles of electrolytic conduction. Special porous oxide films are formed on the anode electrode’s surface when an electric current passes through it. These oxide films act as insulators that effectively prevent any electrons from crossing them. When a voltage is applied to the oxide film, the charges will “pour out” and accumulate on the anode’s surface, forming a single-layer “electrolyte” surrounded by the film.

Once the charge has been accumulated, the closed electric circuit is in a neutral state and no further current flows across the oxide film. This phenomenon is known as the “forward-bias” and is what enables aluminium electrolytic capacitors to maintain their stored charge for a long period of time. The charge can be retained for several days or even several months, depending on the type of capacitor.

When a reverse-bias voltage is applied to the capacitor, the charges will be repelled away from the oxide film and the capacitor will become completely discharged. This phenomenon is known as the “reverse-bias” and is used to discharge the capacitor.

Aluminum electrolytic capacitors are highly reliable devices that can withstand extreme temperatures and are often used in the most critical applications. They are relatively cheap, making them a popular choice for many applications, and are easy to replace in case of malfunction.

The 16JKV47M6.3X5.5 aluminum electrolytic capacitors are specifically designed for use in the most demanding electrical applications. They offer a high capacitance-to-volume, low leakage current, reliable performance, and good stability for the most difficult tasks.
