Aluminum electrolytic capacitors are an essential component used to modify the energy flow, and the UUJ2E470MRQ6ZD series is a highly reliable range produced by Panasonic, which utilize advanced technologies for optimal performance. These capacitors find application in a wide variety of electronic circuits, providing the finishing touch to power supplies, signal conditioning and switching, as well as supplementary circuit protection. Working Principle of UUJ2E470MRQ6ZD Capacitor The UUJ2E470MRQ6ZD utilizes an electrolytic anode, with a vapor-deposited electrolyte. This electrolyte acts as a joule heating element, and when a charged current passes through the capacitor, its internal temperature rises slightly. This produces an exothermic reaction which causes the anode material to expand slightly, increasing its surface area and giving it greater capacity. This, in turn, increases the reaction rate of the electrolyte, causing the heat generated from the current to dissipate more quickly, stabilizing the internal temperature of the capacitor.The anode used in the UUJ2E470MRQ6ZD is typically a foil of aluminum, which is coated with an oxide layer, which essentially acts as a dielectric. To further increase the capacitance, the space between the anode and the oxide layer is filled with a specially formulated electrolyte solution. This electrolyte functions in a similar way to a battery, creating a chemical reaction in which electrons are exchanged between the individual atoms. As the electrons move through the electrolyte solution, an electric current is generated, which is stored in the capacitor. Application Fields The range of UUJ2E470MRQ6ZD aluminum electrolytic capacitors is suitable for a range of general-purpose applications, and are particularly suitable for use in audio systems and computer related circuits, telecom equipment, analytic instruments, and general electronics including voltage-sensitive apparatus, such as micro-processors and resistors. Additionally, these capacitors are often used for power line filtering, and have a high ripple tolerance and low Equivalent Series Resistance (ESR), which is ideal for this purpose. As well as this, the wide range of temperature coefficient options available, meaning that they can be used in a variety of conditions. They are also highly resistant to vibration, making them suitable for use in environments where circuitry is subjected to constant alteration in the frequency of its operating voltage.In addition, the UUJ2E470MRQ6ZD capacitors typically have a high stability to capacitance, meaning that they can be used in critical circuits, such as those in digital signal processing (DSP) and embedded memory circuits. This makes them suitable for use in a variety of applications, such as automated control systems, and within electrical and medical devices. Conclusion The UUJ2E470MRQ6ZD series aluminum electrolytic capacitors are an essential component in a wide range of electronic circuitry, offering a reliable and consistent performance for use in general applications, power line filtering, audio systems, and voltage-sensitive circuits. The combination of a joule heating element, oxide dielectric layer and specially formulated electrolyte solution ensures a consistent and reliable performance, regardless of environment conditions. The UUJ2E470MRQ6ZD series’s wide range of temperature coefficient options, makes them ideal for use in dynamic circuits and various types of equipment.
