<[h1]>ALF40C471DE400 Application Field and Working Principle[/h1]Aluminum electrolytic capacitors are one of the most popular types of capacitors used in a variety of digital and analog circuits. They are typically composed of an anode, or a positive electrode, made of aluminum, which is typically plated in a porous trademarked form called “Alumistar”. The cathode is composed of a conducting material, such as paper, cloth, or foil. The two electrodes are then immersed in an electrolyte solution, typically composed of a mixture of ethanol and water.These capacitors are able to store a large amount of energy and offer an extremely fast response time. Additionally, they are relatively inexpensive to manufacturer, making them an ideal choice for various circuit board designs. The ALF40C471DE400 capacitor is a commercial grade aluminum electrolytic medium-to-high-grade capacitor. It is designed for long life and excellent low-level ripple current capabilities.The ALF40C471DE400 has a voltage rating of 400v DC, a capacitance of 47µF, an operating temperature range of -40°C to 85°C, and a tolerance of ±20% at 25°C. This capacitor is a surface mount part, with a minimum lead space of 0.5mm and a maximum lead spacing of 1.0mm. The part size is 8.0mm x 11.0mm, with a painted overslide case and an epoxy resin overslide to protect the capacitor from environmental elements.When used in a circuit, an electric current will flow from the anode, through the electrolyte, and to the cathode. This flow of current causes a polarization of ions on the anode, which in turn generates an electric field between the two terminals. This electric field stores energy in the form of an electric potential, which can be discharged upon releasing the terminals. The electrolyte also acts as a dielectric constant, increasing the capacitance and thus, the capacitors ability to store more energy.The ALF40C471DE400 is commonly used in DC power supplies, as well as in various signal-filtering and energy-storage circuits. It offers excellent ripple current capabilities as well as a long life due to its high-grade internal components. Additionally, its small size and surface-mount design makes it a great choice for more compact circuit designs. In summary, the ALF40C471DE400 is a commercial grade aluminum electrolytic capacitor that offers high ripple current capabilities, a wide operating temperature range, and an excellent tolerance range. It is typically used in DC power supplies and various signal-filtering circuits where its small size and long life are important advantages.
