Aluminum electrolytic capacitors, abbreviated as AECs, belong to the family of polarized capacitors because their operation requires the application of a particular DC voltage polarity. The physical structure of the AEC consists of an aluminum cylinder, often termed ancan, with two continuous welded plates forming one set of electrodes. The electrolyte, often a low-viscosity liquid mixture of ethylene-glycol containing dissolved salts, fills the space between the two electrodes and provides the required polarization; it also forms an insulative layer of adherent thickness between the electrodes to provide electrical insulation. The other set of electrodes is formed by two or more non-continuous spots of aluminum on the end-plates, usually called a cathode or anode. The dielectric of the capacitor consists of a continuous thin film of a diaphanous, insulating material that lines the anode.

The ESMR421VSN331MP50S is an example of an aluminum electrolytic capacitor. This capacitor offers superior temperature range, superior load life features, and higher voltage ratings than other aluminum electrolytic capacitors. It has a capacitance of 4.21uF and a voltage rating of 4.41V. Furthermore, this capacitor has an operating temperature range of -40 °C to +125 °C and a superior load life rating of 50000 hours. It can be used in a variety of applications due to its impressive performance and long life, such as in switch-mode power supplies and car audio systems.

The working principle of the ESMR421VSN331MP50S is based on the electrolyte-filled anode and a cathode of two or more non-continuous spots of aluminum on the end-plates. The anode and cathode are kept apart and separated by the dielectric, a continuous thin film of a diaphanous, insulating material. When voltage is applied, the electrolyte between the two electrodes passes a current that separates and polarizes the molecules of the electrolyte. This polarization creates an electrical field between the electrodes, in turn producing a capacitance across the capacitor which can store energy. Reversing the applied voltage polarity will cause the separated electrolyte molecules to recombine, thereby releasing their stored energy and discharging the capacitor.

The ESMR421VSN331MP50S is a powerful and reliable aluminum electrolytic capacitor. It features superior temperature range, superior load life features, a high voltage rating and a long life of 50000 hours. Its excellent performance and versatility make it a great choice for a wide variety of applications. It is especially suited for use in power supplies and car audio systems. Its working principle based on electrolyte-filled anode and a cathode of two or more non-continuous spots of aluminum on the end-plates ensures a high level of performance and reliability.
