Aluminum Electrolytic Capacitors

ERWL401LGC472MED0M

Aluminum electrolytic capacitors are electronic components that store electrical energy in the form of an electrical charge like other types of capacitors. However, instead of storing the electrical charge in an insulated material like a dielectric, aluminum electrolytic capacitors use an electrolytic process to store and release the charge. This type of capacitor is composed of two layers of aluminum foil and an electrolyte – usually an aqueous solution of boric acid – sandwiched between them. The charge is stored on the surface of the metal foil and is created by the electrochemical reaction of the electrolyte and the metal foils.

The ERWL401LGC472MED0M aluminum electrolytic capacitor is a high capacity, long life capacitor designed for a variety of applications. It has a rated voltage of 400V and a maximum ripple current of 10A. It is a compact size with low power consumption, making it suitable for a variety of applications, including power supply, DC Motors, Solenoid valves, HVAC, audio equipment, and more. Its low profile design and long life make it an ideal choice for many applications.

The working principle of the ERWL401LGC472MED0M aluminum electrolytic capacitor is fairly simple. When an electric current flows through the electrolyte, it oxidizes the surface of the aluminum foil, creating a layer of aluminum oxide which acts as an insulator and stores the charge. When the current stops, the aluminum oxide dissipates, returning the charge to the capacitor and completing the cycle. This process is repeated each time the current is cycled, creating a steady DC voltage.
