Aluminum electrolytic capacitors are some of the most commonly used capacitors in the world of electronics. They are the most cost-effective solution when it comes to large capacitance values in a small form factor. EKMM451VSN471MR50S is a very popular aluminum electrolytic capacitor manufactured by Kemet Corporation, used in many consumer electronics and industrial electronic devices. This article will discuss the application field and working principle of EKMM451VSN471MR50S.

Application Field of EKMM451VSN471MR50S
The EKMM451VSN471MR50S aluminum electrolytic capacitor is mainly used in self-oscillating switching power supplies, SMPS converters, LED lighting, and other DC-DC converters. It provides high ripple and capacitor life to meet the requirements for high-performance industrial applications. It also has a long life in temperatures ranging from -55°C to 105°C, making it ideal for applications that require a high level of reliability. The EKMM451VSN471MR50S capacitor is also used in high-speed automotive applications such as engine control units and body controllers.

Working Principle of EKMM451VSN471MR50S
The EKMM451VSN471MR50S aluminum electrolytic capacitor is essentially a miniature aluminum foil and paper sandwich, with separations forming two capacitors of equal size and capacity. The inside of the capacitor is filled with an electrolyte and a coating of special epoxy resin. The electrical insulation of the capacitor is ensured by the electric field strength of the outer resin layer.

When the capacitor is connected to an electrical source, it functions like a battery, with the rapid migration of ions to the anode and cathode, respectively, producing current. This current charges the capacitor, creating an electric field between the two plates. As the capacitor charges, the electric field increases, resulting in a decrease in the current flow as the capacitor approaches its full capacity. As soon as the desired voltage is reached, the current flow stops.

The EKMM451VSN471MR50S aluminum electrolytic capacitor is typically used in applications that require high capacitance values in a small form factor. It has a long life in temperatures ranging from -55°C to 105°C, making it ideal for applications that require a high level of reliability.
