Aluminum electrolytic capacitors are a type of electrolytic capacitors commonly used in circuit design. The “400TXW100MEFC16X30” series of capacitors belongs to the family of aluminum electrolytic capacitors. In this article, we will discuss the application field and working principle of aluminium electrolytic capacitors and their many applications.

Types of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are mainly divided into three types: snap-in, screw-terminal and surface mount. The 400TXW100MEFC16X30 series belongs to the screw-terminal type.

Principle of Operation

Aluminum electrolytic capacitors are mainly composed of aluminum foil, paper separator and electrolyte. The anode aluminum foil is made of pure aluminum foil and has an oxide film on its surface. The cathode aluminum foil is made of aluminum foil coated with manganese dioxide (MnO2). The separator is made of paper soaked with electrolyte. When voltage is applied to the electrolytic capacitor, the oxide film of the anode serves as the electrolytic effect, and the oxygen ions generated by the electrolyte are also continuously adsorbed on the oxide film. The oxygen ions form a dielectric with the metal ions to increase the capacitance of the capacitor. At the same time, the electric field and the electrolysis reaction also start to manifest on the surfaces of the anode and cathode, respectively. These processes cause an electric current to flow through the electrolytic capacitor, which makes up the total capacitance.

Features of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors have several distinguishing features. First, the reactive energy of the capacitors is greater than that of the other capacitors. Second, compared to other capacitors, aluminum electrolytic capacitors have a larger capacitance per unit volume. Third, they have a wide range of temperature coefficients. Fourth, they have a wide operating temperature range. Lastly, aluminum electrolytic capacitors have the lowest leakage current and are mainly used for pulse and power applications.
