Aluminum Electrolytic CapacitorsAluminum electrolytic caps are non-polarized electrolytic capacitors which use aluminum foils as an anode, and the thin oxidized film which forms on the surface of that foil as the dielectric. To make the dielectric layer, the anode foil is immersed in an electrolyte containing dissolved salts. When direct current from a power supply is passed through it, oxidation occurs on the surface of the foil, forming a thin film of crystalline insulator. This thin layer is the dielectric of the capacitor and it is what stores the charge in the form of an electric field.The UVK2G470MHD1TN aluminum electrolytic capacitor is a high frequency general purpose capacitor. It has a capacitance of 470µF and a rated voltage of 25 VDC. The temperature range for this capacitor is -40°C to +85°C and it has an impedance of 170mΩ at 125kHz. It is made of aluminum which has been anodized to make an oxide film on the surface. This oxide layer is the dielectric of the capacitor and it allows the capacitor to store energy even when exposed to high frequency tendencies.The UVK2G470MHD1TN aluminum electrolytic capacitor is widely used in power electronics circuits because of its high capacitance values, low costs and high reliability. They can be used in circuits that require low ESR, such as high frequency power converter and switch-mode power supply circuits. They are also used for filtering, decoupling and other applications.The UVK2G470MHD1TN capacitor is composed of several components. On the anode side, there is a thin aluminum foil which is anodized to form an insulating layer. On the cathode side, there is a tantalum layer which acts as an electrolyte and dielectric. The component is then sealed with a casing made of an insulating material to prevent leakage of the electrolyte.The working principle of the UVK2G470MHD1TN aluminum electrolytic capacitor is quite simple. When a direct current is applied, electrons move towards the anode and create an electric field across the dielectric. This electric field serves to store charge and produce a voltage between the plates of the capacitor. The voltage across the plates is proportional to the amount of charge stored in the capacitor.The UVK2G470MHD1TN aluminum electrolytic capacitor is extremely reliable and capable of providing high capacitance values even at high frequency. It is a popular choice for circuits that require high capacitance and low-ESR performance. This capacitor has a wide range of applications, including power supply filters, decoupling, and other types of power electronics circuits.
