UVR2W220MHD is an aluminum electrolytic capacitor. It is generally used in various electrical and electronic circuits, and has become a building block of the current circuit industry. Aluminum electrolytic capacitors are widely used in rectifiers, smoothing circuits and various filter circuits in all fields due to their small volume, large capacity, high capacitance and high reliability. For example, they can be used in computers, infrared remote controls, LED displays, medical equipments and military systems. In terms of working principle, aluminum electrolytic capacitors are composed of two electrodes, an electrolytic paper and an electrolyte. Both electrodes are composed of aluminum foil with additonal oxidated film on it. The negative electrode and the separator are made of aluminum foil and wax paper or glass fiber paper or organic film, and the electrolyte is formed on the plastic film at the difference between the working temperature, high temperature and low temperature. Under the same polarization, because the area of the aluminium foils is large, the capacity of the aluminum electrolytic capacitor is greater than that of the liquid film capacitor and plastic film capacitor of the same size. In the circuit system, when the power is applied voltage greater than the rated voltage of the capacitor, a small amount of current passes through the capacitor, resulting in a dielectric breakdown and an excessive leakage current, so that the capacitor’s insulation resistance decreases, its capacity is reduced, and its functionification is destroyed. Therefore, the rated voltage of UVR2W220MHD should not be beyond the limit of stability.

UVR2W220MHD aluminum electrolytic capacitor is especially suitable for occasions with small volume, high capacity, tight construction and large vibration. It is widely used in military devices such as aerospace, navigation systems, satellite positioning systems, computer systems, communication systems, medical equipment, industrial control systems, etc. It is also used in conventional current and alternating current filter circuits, motor start circuits, peak current absorption and supplementary filter circuits, convertor circuits, blocking circuits and various timing circuits.

The design of aluminum electrolytic capacitors pay attention to the choice of operating temperature and leakage current requirements. Generally, a rated voltage of 10V or more is used for general-purpose aluminum electrolytic capacitors, and the higher the rated voltage, the higher the insulation performance, the higher the reliability and the longer the fatigue life. Aluminum electrolytic capacitors can generally last for more than 10,000 hours, and its endurance time depends on its working environment and the parameters of the installed capacitors. The most important working parameter for UVR2W220MHD is its rated voltage, which is divided into UVR2W220MHD and UVR2W220MHD-A. Both of them are two common multi-voltage aluminum electrolytic capacitors, and the temperature range of them is -40°C to +105°C. The UVR2W220MHD-A is a low-impedance type with low equivalent series resistance (ESR) and large ripple current capacity, while the UVR2W220MHD is more suitable for general use, with low leakage current, low ESR and stable performance.

In conclusion, UVR2W220MHD aluminum electrolytic capacitor is widely used in many occasions due to its small size, large capacity and high reliability. The product is designed for long service life and expected to last for long time under given conditions, and it has different voltage version for different needs. It also needs to pay attention to the voltage rating and temperature range when used, so as to guarantee its long service life and functionality.
