Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor (e-cap) is a cylindrical capacitor with a lumped mass of aluminum oxide electrodes. The electrodes are separated by a thin layer of electrolytic solvent and a solid dielectric material, usually aluminum oxide. This type of capacitor has the highest capacitance and stability in all types of capacitors.

The capacitance of an aluminum electrolytic capacitor is determined primarily by the surface area of the aluminum oxide electrodes and the number of aluminum etched segments in them. The greater the number of etched segments, the lower the capacitance of the capacitor. The quality of the dielectric material also affects the capacitance of the capacitor.

Working Principle of TVAN1112.4

The working principle of the TVAN1112.4 is based on the fundamental principle of capacitance. Capacitance is the ability of a material to store electrical energy in the form of an electric field. When a voltage is applied across the capacitor, it will store charge on its two metallic plates, forming an electric field that stores energy.

The capacitor plates are separated by a thin layer of dielectric material, usually aluminum oxide, thus forming a capacitor. When a voltage is applied across the capacitor, it stores energy in the form of an electric field. The behavior of this electric field is determined by the capacitance, dielectric constant, and surface area of the capacitor plates.

The TVAN1112.4 is a miniaturized, radial-type capacitor that provides high capacitance, high ripple current, and very high insulation resistance. Its low equivalent series resistance (ESR) makes it ideal for high-power, high-performance applications.

The TVAN1212.4 is a highly reliable miniaturized aluminum electrolytic capacitor. It provides excellent high capacitance, high ripple current, and very high insulation resistance, making it suitable for a wide range of consumer electronics, automotive, and aviation applications.
