Aluminum electrolytic capacitors, also known as electrolytic capacitors, are widely used in electronic circuits and often placed alongside resistors and integrated circuits in the circuit. The UVR2G470MHD is an example of such a product, which is a radial-lead aluminum electrolytic capacitor with a diameter of 6.3mm and a length of 11.5mm. It has a rated voltage of 16V and a rated capacitance of 2200 μF. It belongs to the UVR series, which stands for ultra long cycle, ultra long life and ultra long durability.

The external features of the UVR2G470MHD are that its shape is a radial lead aluminum electrolytic capacitor, its electric industry standard is EIA-456-A-98, its color is black and its lead forming is radial. The external material is aluminum, manganese dioxide, lead, rubber and paper. Its operating temperature range is -40 to 85℃, and its allowable ripple current is 2.55 A@100KHz/105℃.

The UVR2G470MHD aluminum electrolytic capacitor is mainly used in oscillation circuits and filtering circuits. Oscillation circuits require stable output current and voltage, so an electrolytic capacitor needs to be used to provide filtering relatively stable current and voltage. Filtering circuits also need a stable output current and voltage, so an electrolytic capacitor is also used to filter the current and voltage and make it stable. The UVR2G470MHD series is particularly suitable for applications requiring a long cycle, life and durability.

The working principle of an aluminum electrolytic capacitor is that when a direct current passes through a sealed capacitor shell, an electric field is formed along the surface of the aluminum foil and the electrolyte is polarized and absorbed. The positive and negative dielectric layers of the electric double layer are formed, and the capacitance is generated by the change in the electric double layer. The operating temperature of the capacitor is directly related to the size of the capacitance. When the temperature is too high, the leakage current of the capacitor increases and the polarization effect decreases, resulting in a decrease of its capacitance.

In conclusion, the UVR2G470MHD aluminum electrolytic capacitor is a radial-lead capacitor with a diameter of 6.3mm and a length of 11.5mm. It has a rated voltage of 16V and a rated capacitance of 2200 μF and belongs to the UVR series. It is mainly used in oscillation and filtering circuits, and its working principle is that when the direct current passes through the capacitor shell, the electric field is formed along the surface of the aluminum foil and the electrolyte is polarized and absorbed to generate the electric double layer, thus forming the capacitance.
