Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors, such as LGU2P681MELA, are a kind of polarized electrolytic capacitor, which is mainly used for energy storage and in high-frequency, filtering and line bypass circuits of various electronic products or systems. It is designed as an electrolytic capacitor but with a mechanical construction of a film capacitor, where two aluminum foils are joined with a dielectric layer of electrolyte (usully an oxide layer) in between them. It consists of an oxide-coated aluminum electrode, a special paper spacer, a glass seal, an inorganic electrolyte, and an external sleeve.The primary components of aluminum electrolytic capacitors are the cathode and anode. The cathode is just a piece of aluminum foil that is coated with an oxide layer. The anode is made of a special paper, which acts as a separator between the positive and negative electrodes of the capacitor. The oxide layer provides the “capacity” to store electric charge and is sealed in the capacitor to prevent reactivity with the electrolyte. The electrolyte serves as an electrical conductor, providing a path for the capacitor to store and release electrical energy.The working principle of an aluminum electrolytic capacitor is quite simple. When a voltage is applied to the capacitor, electrical charges accumulate at the cathode of the capacitor, while charges flow away from the anode and into the negative voltage terminals. This causes the plate that is connected to the negative terminal to become positively charged, while the other plate connected to the positive terminal becomes negatively charged. The electric fields created by the charges cause the plates to store energy.The capacitance of an aluminum electrolytic capacitor is determined by the surface area of the aluminum foil and the distance between the two plates. The larger the distance and the area, the higher the capacitance. This type of capacitor is much more commonly used in high-frequency applications because of its large capacitance and low equivalent series resistance (ESR). This makes it ideal for signal filtering, bypassing, and boosting applications. The LGU2P681MELA is an aluminum electrolytic capacitor that has a capacitance of 680uF at a maximum voltage of 10V and a dissipation factor of less than 0.08.Aluminum electrolytic capacitors are widely used in a variety of applications. For example, they are widely used in power supplies, audio equipment, automotive electronics, and battery backup systems due to their high capacitance and low ESR. They are also often used in RF applications, such as those used in communications and broadcast systems.Overall, aluminum electrolytic capacitors are an important component for a wide range of applications. They are particularly important for providing large amounts of capacitance, low ESR and high reliability in powering and filtering circuits. The LGU2P681MELA is an example of an aluminum electrolytic capacitor, evidenced by its capacitance, voltage, and dissipation factor, that showcases the diverse and essential range of applications these capacitors are suitable for.
