Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (AECs) are widely used in power applications due to their robustness, low inductance, low ESR, and high capacitance values. AECs are the most common type of capacitor, and they are used in almost every type of electronic device. As a result, the understanding of their advantages and shortcomings is important for a successful application.

The EEV-FC1C331P is a polypropylene metallized BOPP film, non-polarized electrolytic capacitor. This capacitor is a popular choice in various applications, and it is highly reliable in power electronic equipment. It is used in the circuit of inverters, DC-DC converters, SMPS, UPS, drives, and more.

Working Principle

The EEV-FC1C331P is an aluminum electrolytic capacitor with non-polarized electrolyte. It consists of two parts: the anode and the cathode. The anode is made of aluminum foil, and the cathode is made of aluminum oxide, which is formed by applying an electric field between the two parts during manufacturing.

When an electric field is applied between the two parts, electrons flow from the anode to the cathode and a dielectric film forms on the surface of the aluminum oxide. This dielectric film acts as an insulator and prevents current flow. The amount of charge stored depends on the thickness of the dielectric film.
