Aluminum Electrolytic Capacitors: UKL1A472KHD application field and working principle

Aluminum electrolytic capacitors are capacitors that reliably store electrical energy and are composed of an anode formed from a pure aluminum foil covered with a metal oxide layer, the layer is formed in a chemical process with etched foil. Additionally, the capacitor has an electrolyte that serves as the cathode and a paper separator. These components are rolled and secured with a welding foil. The capacitor characteristics depend on the thickness of the oxide layer, the electrode spacing, and on the electrolyte used.Aluminum electrolytic capacitors are widely used in a variety of applications such as motors, lighting equipment, power conversion, UPS, switches, electronics, and consumer products. These components offer high capacitance, low ESR, high current handling capacity, high ripple current capability, and requires compact dimensions.The UKL1A472KHD aluminum electrolytic capacitor supports a wide range of applications with its amazing features. This capacitor has a capacitance of 470μF, a maximum voltage rating of 16VDC, and a maximum ripple current of 1600mA, making it suitable for DC-DC converters, high power LED, and high current DC-DC power supplies. The capacitor also offers excellent heat resistance and durability since it is solvent-resistant, vibration-resistant, and has a long shelf life.The main working principle of aluminum electrolytic capacitors is the same for all electrolytic capacitors. Electrolytic capacitors use an aqueous electrolyte as a dielectric material between the anode and a specially treated cathode. Since electrolytic capacitors store a large amount of charge compared to other capacitors, these components are used as energy storage devices in regulated power supplies.When electricity is applied to an aluminum electrolytic capacitor, an electric field is created. This field induces an immediate change in the oxide layer of the anode, which reduces its resistance, allowing current to flow from the electrolyte to the anode. This charge is stored in the anode and the capacitor is charged. When the electricity is removed from the capacitor, the anode\'s oxide layer increases its resistance, thus preventing the current from flowing through it, and the charge stored in the capacitor slowly decreases.In summary, the UKL1A472KHD aluminum electrolytic capacitor is an ideal choice for a wide range of applications due to its high capacitance, low ESR, high current handling capacity, and high ripple current capability. The capacitor works on the same working principle as other electrolytic capacitors, where an electric field is created and charge is stored in an anode. This allows the capacitor to store and deliver electric energy.
