What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is an electronic device commonly used for various electrical applications ranging from signal processing to power supply switching. It consists of two aluminum foils, with a thin layer of insulating oxide film between them, that are rolled up and then inserted into an aluminum can. The two foils act as a sandwiched conductor, and the oxide film acts as the dielectric. It can withstand high voltages and has low internal power losses due to its high surface area and wide temperature range.

477KXM100M Application Field and Working Principle

The 477KXM100M aluminum electrolytic capacitor is a high-quality component designed for medium voltage applications. It is ideal for use in high-voltage applications such as inverters and motor drives. It is capable of safely handling up to 400V withstanding the effects of electrical noise and harsh environmental conditions.The 477KXM100M capacitor contains spiral wound electrodes with an aluminum foil as the anode and a dielectric of a conductive polymer as the electrolyte. The dielectric is immersed in an electrolyte material. The structure of the device gives it excellent capacitance, current leakage, and insulation resistance values over a wide temperature range.The aluminum foil and the dielectric layers form a compression joint which keeps them in contact with each other electrically. The electrode has a dielectric breakdown voltage of 400V to withstand high voltage spikes. It also has a low equivalent series resistance (ESR) for low power dissipation. The capacitor also has high capacitance because the aluminum has high surface area to volume ratio.When the capacitor is connected to a DC power supply, the electric field between the conductive oxide layer and the aluminum foil causes charge to move from one layer to another. The electric field increases the electric charge stored, which is referred to as the capacitance of the device. The value of capacitance is determined by the surface area, thickness of the oxide layer, and the dielectric constant of the oxide layer.The 477KXM100M aluminum electrolytic capacitor is a reliable component for applications that require a high-voltage rating and low power dissipation. It has excellent capacitance, current leakage, and insulation resistance values that can withstand environmental conditions. It also has a low ESR for low power dissipation and a dielectric breakdown voltage of 400V to handle electrical noise and voltage spikes. With its high voltage rating and low power dissipation, this capacitor is perfect for use in high-voltage applications such as motor drives, inverters, and more.
