Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors, popularly known as aluminum electrolytes, are electrochemical devices that combine aluminum and electrolytes to form capacitors. These capacitors are widely used in applications ranging from audio-video circuitry to high frequency motors. With its unique features, the aluminum electrolyte capacitor is an important component of many power supplies, radio-frequency transmitters, and audio-video components.This article will focus on the UCD1J471MNQ1MS application field and working principle. UCD1J471MNQ1MS is an aluminum electrolytic capacitor which is designed for long-term operation at continuous high voltage and high current. The UCD1J471MNQ1MS is a polarized, non-polarized capacitor, available in a cylindrical, axial-leaded form, with a voltage rating up to 100V and an operating temperature range from -40C to equipment designed for 85C.The UCD1J471MNQ1MS is primarily used in high frequency and switching power supplies, as well as audio-video equipment, computer and communication equipments and other automotive and industrial control system circuit applications. It has a high capacitance to voltage ratio, and low series inductance, enabling it to be used in wide range of applications.The working principle of the UCD1J471MNQ1MS capacitor is quite simple, it is based on the phenomenon of double layer capacitance (DLC), caused by the two layers of electrochemically formed metal oxide. The first layer is formed on the electrolyte-facing side of the aluminum sheet and is known as the injection layer. This layer has a very high conductivity, allowing charges to flow from the aluminum sheet into the substrate. The second layer is formed on the substrate-facing side of the aluminum sheet and is known as the blocking layer. This layer is much less electrically conductive and is designed to block the passage of charge from the substrate up through the injection layer and into the aluminum sheet.The electrical field between the two layers of metal oxide governs the capacitance of the UCD1J471MNQ1MS. When a voltage is applied between the aluminum sheet and the substrate, the capacitance of the capacitor can change. This is due to the fact that when the voltage is increased, the electrical field within the two layers intensifies, increasing the capacitance.In conclusion, the UCD1J471MNQ1MS is an aluminum electrolytic capacitor which is designed for long-term operation at continuous high voltage and high current. It has a high capacitance to voltage ratio, and low series inductance, enabling it to be used in wide range of applications such as high frequency and switching power supplies, as well as audio-video equipment, computer and communication equipments as well as other automotive and industrial control system circuit applications. The working principle of the UCD1J471MNQ1MS capacitor is based on the phenomenon of double layer capacitance (DLC). When a voltage is applied between the aluminum sheet and the substrate, the capacitance of the capacitor can change due to the electrical field between the two layers of metal oxide.
