Introduction to Aluminum Electrolytic CapacitorsAn aluminum electrolytic capacitor is a type of capacitor which utilizes an anode of electrolytic aluminum foil with an oxide surface layer as the electrolyte along with a cathode of non-soluble material. It is one of a type of capacitors that typically has the highest capacitance per unit volume. The anode has a larger surface area compared to a conventional capacitor, thereby delivering a greater capacitance with a relatively low equivalent series resistance (ESR). This makes aluminum electrolytic capacitors suitable for high-frequency as well as low-frequency use.EMVA4R0ADA471MF80G Application Field and Working PrincipleThe EMVA4R0ADA471MF80G is an aluminum electrolytic capacitor and it is designed primarily for use in applications that require high capacitance values in a relatively small form factor. It has a maximum operating voltage of 600 and a capacitance of 4700uF.The working principle of the EMVA4R0ADA471MF80G is similar to that of any other type of aluminum electrolytic capacitor. A thin anode aluminum foil is anodically oxidized to form a capacitive dielectric film on the surface, which is insulated from a cathode foil made of non-soluble material. The anode and the cathode are separated by a spacer and soaked in an electrolytic solution, increasing the surface area of the electrolyte, thus forming a large capacitance.The EMVA4R0ADA471MF80G is constructed using high-grade electrolytic aluminum materials, which ensure robustness, reliability, and durability. It is also designed with an organic liquid electrolyte system which helps reduce the equivalent series resistance and ripple current. The low equivalent series resistance values help in utilizing the capacitance characteristics of the EMVA4R0ADA471MF80G at higher frequencies.The EMVA4R0ADA471MF80G is recommended for applications such as power supplies, voltage stabilization circuits, PFC circuits, and high-speed DC-DC converters. It is also suitable for operation in harsh environmental conditions.Advantages of the EMVA4R0ADA471MF80GThe EMVA4R0ADA471MF80G has several advantages when compared to other aluminum electrolytic capacitors. The main advantages include:• High capacitance: The EMVA4R0ADA471MF80G have a high capacitance of 4700uF, which is significantly higher than most other aluminum electrolytic capacitors.• Low current leakage: The EMVA4R0ADA471MF80G are designed with an organic liquid electrolyte system, which helps reduce the equivalent series resistance and ripple current.
