Aluminum Electrolytic Capacitors are electronic components designed to store electrical energy. They are commonly used as stabilizers in power supplies for a variety of applications. The 200USG330MEFC20X25 is one such capacitor that is specifically designed for high frequency applications. This section explores the 200USG330MEFC20X25 application field, as well as its working principle.

Application Field

The 200USG330MEFC20X25 is a high frequency, non-polarized aluminum electrolytic capacitor. It is available in various voltage ratings from 4V to 630V. It has a low Equivalent Series Resistance (ESR) and high temperature operation capability. It is often used in switched mode power supplies, multi-band RF amplifiers, DC-DC converters, and active filters. Additionally, it is employed in audio, video, and telecommunication systems, such as tuned amplifiers, equalizers, oscillators, and servo amplifiers.

Working Principle

An aluminum electrolytic capacitor primarily works by storing electrical charge on electrolytic media inside an aluminum oxide layer. A pair of metal plates encased in a container are placed in an electrolyte solution. When power is applied, positive ions of the electrolyte migrate to the negative plate where they form an aluminum oxide layer. This layer creates a high dielectric value and acts as an insulator. Negative ions from the electrolyte arrive at the positive plate and complete the circuit. This allows electrical charge to be stored and released when needed.

Additionally, the 200USG330MEFC20X25 features a special type of anode construction known as “face frame” technology. This makes it possible to achieve a higher capacitance within a limited space. The metal plates are wound around a spindle and fastened in place with a thin ceramic frame in order to create larger “real estate” for charge storage. This reduces internal impedance and increases the capacity to store electrical charge.

Conclusion

The 200USG330MEFC20X25 aluminum electrolytic capacitor has been designed for use in high-frequency applications such as switched mode power supplies, multi-band RF amplifiers, DC-DC converters, active filters, and tuned amplifiers. It operates on the principle of storing electrical energy in an electrolyte solution and utilizes a unique face frame anode construction to achieve a greater capacitance in a smaller form factor. This makes it an ideal solution for applications where space is limited and increased charge storage is required.
