Aluminum electrolytic capacitors (ELCs) are electrical devices that are composed of two pieces of aluminum foil that are wound together with electrolytic material between them. The electrolyte acts as a dielectric, allowing electrons to pass between the two aluminum plates, thus creating a capacitance effort. ELCs are used in many different applications, including power supplies, automotive, medical and industrial electronics, and are also used in various audio visual applications. The UEP1A222MHD1TN aluminum electrolytic capacitor is specifically used in power applications such as switching power supplies, and car audio systems.

Application Field

The UEP1A222MHD1TN ELC is specifically designed for use in power applications where high-power efficiency is desired. This type of capacitor is designed to provide high- frequency noise dampening, which makes them ideal for applications such as switching power supplies, car audio systems, high-fidelity audio systems and other power electronics. In these applications, ELCs are used to decrease the high-frequency ripple on the output, improve input power factor, and protect key circuits from being damaged by thunder and other high-frequency noises.

The UEP1A222MHD1TN aluminum electrolytic capacitor is used to reduce the threat of noise and undesired high-frequency current generated by switching power supplies or car audio systems. The unit has a ripple current capability of at least 800ma (at 70°C), and is able to maintain its speculated performance level for up to 4500 hours. Additionally, the unit is designed with a compact, DIP-style design that requires minimal space.

Working Principle

An ELC is composed of two aluminum plates, each coated with electrolyte, and separated by an insulating material. When the DC voltage is applied to the ELCs, a chemical reaction forms on the aluminum plates and forms a thin layer of oxide. This oxide acts as a dielectric between the plates, and allows electrons to pass through, creating an electrical current. The amount of current is determined by the amount of capacitance, which is indicated by the size of the ELC. The capacitance of an ELC is indicated by its capacitance value, which is usually expressed in Farads. The UEP1A222MHD1TN ELC has a capacitance value of 220 µF.

When used in circuits, ELCs can be wired together in parallel or in series. When wired in parallel, the capacitance value increases because more paths of electrons are created since the capacitors are placed side by side, allowing alternate electrons to move through each of the plates. When ELCs are wired in series, the capacitance value decreases, as the total capacitance is reduced since the electrons must pass through all of the plates before completing its cycle and returning to the power source. The UEP1A222MHD1TN ELC is designed to be wired in parallel, as its ripple current capability increases when the capacitors are connected in parallel.

ELCs are used in a wide variety of applications including, automotive, medical, industrial, and audio/visual applications. The UEP1A222MHD1TN ELC is specifically designed for use in power applications, where high-frequency noise dampening is desired. Its compact DIP-style design provides space efficiency, and its ripple current capacity (at 70°C) is at least 800ma. When wired in parallel, the capacitance value increases to provide longer operation time and enhanced performance.
