Aluminum electrolytic capacitors perfectly meet the needs of most electronic circuits, and the part number 385USC270MEFC22X50 is designed under this category. This article will explain the application field and working principle of the part accordingly.

Application Field

The part number 385USC270MEFC22X50 belongs to non-solid aluminum electrolytic capacitors. This type of capacitor are advantageous in electronic and nuclear operation systems across the board. An aluminum electrolytic capacitor combines the applied potential difference of an anode and a cathode while using aluminum film and electrolyte paper as a separator. The device efficiently bypasses interference caused by electromagnetic radiation, electrostatic fields, anions, and cations, providing stable and reliable operation. In addition, the385USC270MEFC22X50 is capable of working consistently even under low ambient temperatures, making it an ideal choice for peripheral and control circuits in a variety of unconventional settings.

Working Principle

The 385USC270MEFC22X50 utilizes an extremely thin aluminum electrolytic capacitive element. Its two electrodes are assembled into a cylindrical multi-layer electrostatic capacitor and the cut foil section is then placed through tension before being sealed into a closed environment with electrolyte. The two electrodes cooperate to form a strong electric field between them. When a voltage is assigned to the electrodes (separated by electrolyte), the electric field becomes very strong and determines the capacitance between the electrodes, which in turn influences the current properties.

The 385USC270MEFC22X50 also features a special electrolyte: a non-solid paste-type brush-on electrolyte which is absorbed directly into the paper layer on the anode side and between the anode and the cathode. This feature allows the cap to operate in dynamic and low-temperature conditions, which makes it ideal for applications in nuclear facilities, rockets, or satellite systems.

In general, the part number 385USC270MEFC22X50 can handle larger peak voltage fluctuations and better corrosion resistance during long-term operation. As such, it is more suitable for applications in heavy electronic industry, military, aerospace, medicine, audio equipment, and power supply systems.
