Aluminum electrolytic capacitors are used in a wide range of applications in consumer electronics, automotive electronics, computers and communication equipment, and industrial control systems. The UCX1H122MNQ1MS is an example of such a capacitor, used for power supplies, DC-DC converters, filtering, and oscillation circuits, especially in the fields of automotive, medical and other applications.

The UCX1H122MNQ1MS is an axial-shaped, non-solid aluminum electrolytic capacitor featuring low leakage current and good insulation performance. It consists of a non-solid electrolyte, an anode aluminum foil, a cathode aluminum foil, a PPS insulated case, and a phenol resin sealant. The size and capacity of the capacitor is 2 x 8mm and 122µF. Its working voltage is 16V.

In terms of working principles, the UCX1H122MNQ1MS capacitor is a polarized electrolytic capacitor with a cathode and an anode. The anode is made of an aluminum foil that is etched and oxidized to form a large surface area, followed by a very thin insulating oxide layer. The cathode is a piece of aluminum foil, which is then coated with a mixture of manganese dioxide, silver oxide and other materials. These serve to make the cathode highly conductive and capable of electrolytic current.

Once the DC voltage is applied, electric current passes through the electrolyte and the oxide layer, which causes the Debye layer (the layer between the anode and cathode) to form. This layer is responsible for the electric charge exchange between the oxide layer, anode and cathode, thus creating a capacitance. The capacitance of the capacitor depends on the length of the Debye layer, which increases with higher applied voltage.

The UCX1H122MNQ1MS capacitor is a surface-mounted aluminum electrolytic capacitor that provides excellent performance in applications such as power supplies, DC-DC converters, filtering, and oscillation circuits. Its non-solid electrolyte, anode and cathode foils, PPS insulated case, and phenol sealant allow it to offer excellent performance — low leakage current, good insulation performance and a long lifetime. As a result, it is ideal for use in applications that require reliable power supplies, and capable of handling a wide range of voltages.
