Aluminum electrolytic capacitors are one of the most widely used electronic components in the electronics industry, with a wide range of applications. Among them, RFS-50V470MH4#5 aluminum electrolytic capacitors are also widely used. This article will introduce what is and are RFS-50V470MH4#5, their application fields and their working principles.

RFS-50V470MH4#5 - Overview

RFS-50V470MH4#5 aluminum electrolytic capacitors are polarized aluminum electrolytic capacitors. The "50V" in its name means that its rated voltage should not exceed 50V. The "470" represents the capacitance, which is 470uF, and "#5" is a specific code. It is a cylinder type, its physical dimensions are Length (L): 25.8mm, Diameter (D): 12.7mm, without rated overpressure. The external epoxy sealing enables it to be resistant to shock and vibration. Its life expectancy is higher compared with other capacitor types, and its performance is stable in a wide temperature range.

RFS-50V470MH4#5 - Applications

RFS-50V470MH4#5 capacitors are most widely applied in circuits with higher load current, where fitting with small-sized capacitors becomes necessary. Therefore, they are ideal for use in power supply circuits such as those in LCD monitors, desktop computers, audio systems, and digital cameras. Moreover, their low equivalent series resistance (ESR) and high ripple current capacity make them suitable for employment in memory backup and cache memory applications.

RFS-50V470MH4#5 - Working Principle

The construction of an aluminum electrolytic capacitor includes an anode aluminum foil, a cathode foil, and coated separator paper, which are all soaked with electrolyte. When a DC voltage is connected between them, the anode aluminum foil will increase its oxidation so as to form a layer of aluminum oxide, thus separating positive and negative electrodes. As a result, the capacitor can store an electric charge, and thus capacitance is formed. According to the different anode oxidation layers and amounts of electrolyte added, aluminum electrolytic capacitors can be divided into four categories: Screw type, Radial type, Snap-in type, and Lug type.

RFS-50V470MH4#5 capacitors are cylindrical aluminum electrolytic capacitors. The poles are connected by solder pins, and their core part is completely filled with electrolyte, so as to ensure that the surface of the positive and negative electrodes are fully wetted with electrolyte.

When an electrical signal flows through the RFS-50V470MH4#5 capacitor, electrons will pass through the anode aluminum foil, thus forming an electric current. At the same time, the electric current will charge the aluminum oxide film, thus forming a stable electric field. This electric field will affect the movement of electrons, thus generating polarization.

Conclusion

RFS-50V470MH4#5 aluminum electrolytic capacitors have wide application in power supply circuits such as those in LCD monitors, desktop computers, audio systems, and digital cameras. Generally, their life expectancy is five times higher than other capacitor types, and their performance is stable in a wide temperature range. Their structure includes an anode aluminum foil, a cathode foil and coated separator paper, which are all soaked with electrolyte. When an electrical signal flows through the RFS-50V470MH4#5 capacitor, electrons will pass through the anode aluminum foil, thus forming an electric current, and the electric current will charge the aluminum oxide film to generate polarization.
