Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors consisting of an anode typically formed by an aluminum foil with an etched surface covered with a dielectric film, and a cathode typically made up of an aluminum oxide compound. This type of capacitor is efficient at storing electric charge and can have a capacity up to 10,000 times larger than comparable ceramic capacitors.The LKG1H472MESABK electrolytic capacitor is a high-performance type of aluminum electrolytic capacitor with a high rated voltage of 470V and high capacitance of 4700µF. The device is designed with an axial form factor and features safety venting and long-life characteristics. This makes it suitable for use in a variety of applications including bypass, decoupling, and high-frequency filtering circuits.

Working Principle

The LKG1H472MESABK aluminum electrolytic capacitor functions by storing electrical energy in the form of a static electric charge between a dielectric material and an anode foil. Capacitors are designed with a dielectric, which is an outer layer that insulates the anode from the cathode. As voltage is applied between the anode and cathode, the electric potential draws electrons from the anode, which can then pass through the dielectric and create a static electric charge between the anode and dielectric.The capacitance of an electrolytic capacitor is determined by its physical size and the dielectric material used. Larger capacitance values require a greater amount of the anode material to be etched away, resulting in a larger surface area for charge accumulation. Because of its higher rated voltage, the LKG1H472MESABK capacitor has a larger internal etching surface area, allowing it to store a higher capacitance value than a similarly sized device with lower voltage rating.

Application Field

Aluminum electrolytic capacitors, such as the LKG1H472MESABK, are widely used in a variety of electronic circuits due to their high capacitance values and higher operating voltages. The device is typically used in high-frequency switching circuits, DC-DC converters, and other high-voltage circuits where capacitors with larger capacitance values are required.The device is also well suited for decoupling applications due to its low equivalence series resistance (ESR) and high ripple current tolerances. Decoupling involves connecting a capacitor in parallel with a signal or power line to reduce the effects of noise and interference on a system. By connecting a capacitor with a high ESR and higher ripple current tolerance to the supply, it will absorb the interference and protect the device from any harmful power fluctuations.The LKG1H472MESABK capacitor is also often used in bypass applications. Bypass capacitors are used to block DC current from passing through a signal line while allowing AC current to continue to flow. This makes it ideal for use in high-frequency filtering circuits, allowing AC signals to flow through a signal line while blocking any DC signals.In conclusion, the LKG1H472MESABK aluminum electrolytic capacitor is a high-performance device designed for use in a variety of applications including decoupling, bypass, and high-frequency filtering circuits. The device is well suited for these applications due to its high rated voltage, high capacitance values, low ESR, and high ripple current tolerance.
