Aluminum electrolytic capacitors are electric components that store charge and electricity in electric systems. Among all kinds of capacitors, aluminum electrolytic capacitors have the highest specific capacitance and are widely applied in many non-polar electrical circuits. The UCS2E181MNY9 is a kind of aluminum electrolytic capacitor developed by the company based on its successful experience in capacitor manufacturing. It is especially popular among electronic application units.

The UCS2E181MNY9 is a radial, non-polar aluminum electrolytic capacitor with a snap-in terminal. Its cylindrical body is made of aluminum. The capacitor is specially produced with a rated voltage of 450VDC. Its capacitance ranges from 10μF to 100μF. This capacitor measures 18mm X 8.3mm X 31mm and features a max. ripple current at 120Hz of 2850mA.

The UCS2E181MNY9 is mainly used in high quality non-polar electronic safety equipment such as emergency power supplies, electronic power supplies, professional power amplifiers as well as filters and communication systems. Its long life makes it a reliable choice to serve various industrial and consumer applications.

The working principle of UCS2E181MNY9 is based on electrochemical double layer capacitance. In an electrolytic capacitor, anodic aluminum forms an insulating layer of anodic aluminum oxide on the surface when the rated voltage is applied. This layer acts as the dielectric of the capacitor. The two electrodes of the capacitor are formed by two faces of the same aluminum plate which are separated by the anodic aluminum oxide layer with one face (positive electrode) covered by it and the other face (negative electrode) exposed. The electrolyte serves as a medium of electronic exchange between the electrodes and provides mobility to the electrical ions through electron current.

When charge is applied, the positive electrode (anodic aluminum oxide layer formed on the aluminum plate) attracts the positive ions, while the negative electrode (exposed aluminum plate) attracts negative ions. This creates a double-layer electric field between the oxide layer and the electrolyte. The capacitance of the capacitor is dependent on the area of the oxide layer, thickness, oxidation time and the properties of the electrolyte. The characteristics of the capacitor are determined by the combined effects of the electrode, dielectric and electrolyte.

The UCS2E181MNY9 is the perfect choice for electronics demanding high quality and is highly dependable. It offers reliable performance over the temperature range from -40 °C to +105 °C and has a wide range of application areas in various types of electrical and electronic systems.
