Aluminum Electrolytic Capacitors are electronic components that store energy using an electric field in a dielectric, typically without external connections. The ESMG160ELL472MN20S is a product line of aluminum electrolytic capacitors manufactured by Murata, and includes a wide range of capacitance values. This product line can be used for a variety of applications, including power supply filtering, energy storage, frequency compensation, transmission and noise suppression, AC motor control, and more.

The base principle of the ESMG160ELL472MN20S is the same as that of any other aluminum electrolytic capacitor, which is to store energy within the electric field present between two thin, flat aluminum foil plates that have an insulating material in-between them. This energy-storing phenomenon occurs when there is a potential difference across the plates. When this occurs, the electric field created induces a charge onto the two plates, and creates a voltage. This voltage is then stored in the capacitor and can be transferred to other components for various applications.

In practice, the capacitor plate is not merely an infinite flat conductive plate but rather consists of a metal foil with etched or punched Electrolytic Capacitor patterns. The metal foil is called the \'Anode Foil\', while the material that is punched or etched away from the anode foil is called the \'Cathode Foil\'. The etched forms act as a pattern which increases the capacitance of the capacitor, while increasing its lifespan and reliability. The two foils are then separated by a layer of dielectric, which can be in the form of an electrolyte impregnated paper, oil-filled paper, a film such as Polystyrene etc.

The quality of the metal foils is also important to achieve efficient current performance. The Murata aluminim electrolytic capacitors of the ESMG160ELL472MN20S series are created with high-quality metal foils that provide an increased capacitance and are less susceptible to leakage. This quality is achieved by forming thin layers of oxide which is created on the surface of the electrodes by anodization using DC bias voltage.

In order to construct a practical capacitor using the ESMG160ELL472MN20S, a few simple steps need to be followed. First, the anode and cathode foils are securely connected together and then a dielectric is added. Next, a metal terminal is placed around the anode and cathode assembly. Finally, the metal terminal is connected with an insulator and the entire assembly is then filled with an electrolyte, which will complete the process.

Overall, the Murata ESMG160ELL472MN20S aluminum electrolytic capacitor is a versatile product line suitable for a variety of applications. The capacitor plate assembly is made of high-quality materials and is designed for long-term electrical performance. The ESMG160ELL472MN20S capacitors can efficiently store potential differences across its plates for energy storage, AC motor control, noise suppression, power supply filtering, and other applications.
