Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are most commonly used in a wide range of electronics, such as computers, televisions, audio systems, and power tools. The LNR2E473MSE aluminum electrolytic capacitor is a great example of the power and high performance that these components offer. ApplicationsAluminum electrolytic capacitors are most often used to provide high-voltage, high-capacity energy storage solutions. The LNR2E473MSE is a great option to use when a large amount of energy needs to be stored in a relatively small package. This part is well-suited for applications such as DC-DC converters, high current filtering, general-purpose DC filtering, and snubber circuits.These capacitors can also be used in high-frequency applications such as radio antennas, electromechanical transducers, and power line systems. Additionally, they are commonly found in automotive applications as well, such as ABS and stability control systems, voltage converters, engine starters, and turbochargers.Working PrincipleAluminum electrolytic capacitors are constructed with two aluminum foils separated by a piece of paper that is saturated with an electrolyte. When voltage is applied, a small electric field is created in the electrolyte, which causes electrons to be drawn toward the anode to create a positive charge. The anode has a slightly larger surface area than the cathode, so more electrons are attracted there and a higher voltage is created. The foil layers are carefully sandwiched together and then sealed in an airtight container in order to keep the electrolyte from evaporating. This design also helps to prevent any gassing from happening, which can reduce the capacitor’s lifespan.The LNR2E473MSE capacitor is capable of withstanding a maximum operating temperature of 125°C and has a maximum rated voltage of 450V DC. Additionally, the capacitor has a maximum ripple current rating of 4.7A and a maximum leakage current of 0.2mA. This part also features an exceptionally long lifespan, rated for 10,000 hours of continuous use at 105°C.ConclusionThe LNR2E473MSE aluminum electrolytic capacitor is a great choice for high-voltage, high-capacity applications. With its high tolerance for temperature and high ripple current rating, this part is suitable for a wide range of high-frequency and automotive applications. Its long-life design and effective gassing suppression makes it an ideal choice for high-end consumer products that require reliability.
