Aluminum electrolytic capacitors, primarily used in power supplies, consist of two aluminium foils, which form the electrodes and electrolyte or a solid dielectric (the insulation layer). Its high energy density, reliability and low cost make it a popular choice in power and consumer electronics application. UVZ1E220MDD1TA is an aluminum electrolytic capacitor in this family, which is quite popular due to its high voltage and long life.

The UVZ1E220MDD1TA is a radial aluminum electrolytic capacitor and features the base E capacitance type. The voltage rating is at 6.3V (this is voltage max surge and continuous dissipation capacity, called U max) and capacitance of 220uF (electrical capacitance of the capacitor, measuring, F). The capacitor is polarized, it means that it has two different electrodes, with a positive and negative polarity, thus the correct way of installing it in the circuitry is important for ensuring proper operation and safe operation. This component has a tolerance of ± 20% on the capacitance value, which means that, even if the capacitor is left unused over time, its electrical characteristics remain stable.

The temperature range the capacitor operates in is between -40°C and 85°C, and its storage range is between -40°C and 105°C. This ensures a long life-span and reliable performance. Within this storage range, the capacitor can represent certain electrical characteristics such as its Dissipation Factor (DF). The DF value indicates the ratio of the energy dissipated in the dielectric medium (capacitor) compared to a perfect capacitor with no dissipation across it. This capacitor has a DF value of 0.04, which means that its energy dissipation is quite low. The capacitor also features a Minimum Insulation Resistance (MIR), which indicates the leakage of current across the capacitor in a conductive medium.

The UVZ1E220MDD1TA is suitable for high-voltage application fields including computer motherboards, video cards, and mobile phones. It is also used in low-voltage applications such as audio amplifiers, telecom and instrumentation circuitry. The capacitor is also used in automotive and industrial electronics, due to its high surge voltage capability and high temperature operation.

The working principle of an aluminum electrolytic capacitor is based on its construction. The two aluminum foils are isolated from each other, separated by insulating layers, and electrolytic paste is added between the electrodes to provide anionic current conduction. During operation, the capacitor dissipates energy from the positive electrode to the negative electrode. This anionic current is determined by the area of the electrodes, temperature, electrolyte type, voltage level, and other related parameters. So the bigger the anionic current, the greater the energy storage capacity.

The UVZ1E220MDD1TA is an excellent high-voltage aluminum electrolytic capacitor which is suitable for a variety of applications. Its long life and low DF value make it a reliable choice for high-power applications. It also features a wide temperature range and minimum insulation resistance, which keeps it safe under high voltage operations, and ensures reliable performance.
