Aluminum Electrolytic Capacitors: MAL203858221E3 Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors, belong to a type of capacitor that uses its tendency to generate electrolytic action. They are the most common type of capacitors found in electronic circuits. The main components of the aluminum electrolytic capacitors are two aluminum foils cut into small sizes, with a thin oxide layer coated on one side of them. One of the aluminum foils is made with an oxide layer, insulated and wound into a spool or coil, while the other one is just placed with a non-conductive layer between them.If the two terminals of an electrolytic capacitor are connected with an electrical voltage, a certain amount of positive charge is stored on one terminal and negative charges on the other terminal. Theoretically, the positive charge will make the external circuit with the same positive polarity exchanging electrons to the other terms. While the negative charge will exchange electrons with the outside circuit with the same negative polarity, thus forming a capacitor.The MAL203858221E3 has become one of the leading electrolytic capacitor products in the market now. It is a RoHS-compliant electrolytic capacitor with an anode made of aluminium foil. It has a good withstand voltage of mature 1600V and an isotropic high temperature of -55°C to 150°C. Moreover, it features other excellent characteristics, such as lengthy life, stable performance, low leakage current, and high volumetric efficiency, making it ideal for use in a wide range of applications in power electronics, storage battery, consumer electronics, frequency converter, etc.When using the MAL203858221E3 aluminum electrolytic capacitor for a specific application, the working principle can be broken down into several stages. First, the two aluminum foils form anode and cathode respectively, and then the metal oxide film is formed on the anode. Secondly, with the application of an electric voltage between the two electrodes, a current will be generated and pass through the metal oxide film. Thirdly, dielectric polarization will be produced, because the anode reaction will help the anode particles between the two foils become polarized, resulting in the accumulation of electric charges. At last, current conduction will stop, so as to form an electric field between the two foils.Thus, the MAL203858221E3 aluminum electrolytic capacitor plays an essential role in the wide range of above applications, as it takes advantage of its highly stable performance and low leakage current. To ensure that it works properly, it\'s necessary to be sure that the capacitor is applied in the correct working environment and at the specific working voltage.In conclusion, the MAL203858221E3 aluminum electrolytic capacitor is a perfect choice for applications ranging from power electronics to frequency converters. It has a wide temperature range, stable performance, and form a high-quality electric field to ensure a low leakage current. Moreover, it also provides prolonged lifetime and volumetric efficiency which makes it highly competitive on the market. With its high working voltage, this electrolytic capacitor is an important tool for anyone seeking a reliable connection in an electronic circuit.
