Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are widely used in industry, telecommunications, appliances and other electronic applications due to their high capacity, robust construction and low leakage current. The TVA1439 series is a particular type of aluminum electrolytic capacitor specifically designed for high reliability applications. This paper will discuss both the application fields and working principle of the TVA1439.The TVA1439 is designed with a unique, elliptical-shaped aluminum foil and a highly-specialized electrolyte compound. As a result, this capacitor has an ultra-high intensity design that offers superior reliability, superior efficiency, and an extended life cycle even at extreme temperatures. It is designed for applications including high-voltage power supplies, high power rectifiers, DC power supply filters, high-current inverter, DC/DC Conversion and UPS systems.When it comes to the working principle, the TVA1439 is an electrolytic capacitor, which stores energy in an electric field formed by electrolytic solution between two electrodes. This electric field enables the capacitor to store electrical energy. The aluminum electrolytic capacitor consists of two parallel metal surfaces, having an electrolyte stored between them. Each of the two electrodes is made from highly-conductive aluminum foil with an oxide layer. On one side of the capacitor, the aluminum foil is etched, which creates an uneven surface with very small holes. This helps the electrolyte solution to enter and reach the surface as the capacitor charges up. The other electrode is covered with a special film called dielectric.When the capacitor is connected to a power source, electrons are transferred from the negative plate to the positive plate, as the power source charges up the capacitor. If the capacitor is used to store energy, the electric charge in the capacitor adds up until it reaches the breakdown voltage of the aluminum electrolytic capacitor. As the charge or voltage increases, so does the electric field between the plates, which increases the capacitance. This makes the capacitor more efficient in storing electric energy.In conclusion, the TVA1439 is a highly reliable, cost-effective aluminum electrolytic capacitor designed with an ultra-high intensity design, which offers superior reliability, superior efficiency, and extended life cycle even at extreme temperatures. It is designed for applications such as high-voltage power supplies, high power rectifiers, DC power supply filters, high-current inverter, DC/DC Conversion and UPS systems. Furthermore, the working principle of an aluminum electrolytic capacitor is based on the transfer of electrons from the negative plate to the positive plate, creating an electric field between two electrodes, which enables it to store electrical energy.
