Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrochemical capacitors which use aluminum oxide layers as the dielectric material. They are one of the most common types of capacitors, offering considerable charge storage capacity for their relatively small size. The B43505E2687M87 is one such capacitor of the aluminum electrolytic variety, which is typically used for industrial and consumer electronics applications. When an electric potential is applied across the anode and cathode of the aluminum electrolytic capacitor, electrons are attracted to the anode and protons are attracted to the cathode. This creates a weak electric field across the oxide layer, and positive ions are driven out of the oxide region to the cathode side. This polarization process creates an electric charge buildup in the capacitor, and the capacitance of the capacitor is directly proportional to the potential drop across the device.The B43505E2687M87 aluminum electrolytic capacitor offers a capacitance of 4700µF and a voltage rating of 35V. Common applications for these electrolytic capacitors include power back-up, power supply filtering, high current discharge, high frequency filtering, and electroacoustic systems. Ideally the capacitor should be operated within its voltage rating and at temperatures no higher than -40°C. One benefit to using an aluminum electrolytic capacitor is its low equivalent series resistance (ESR). Low ESR allows the capacitor to store energy efficiently and serve as a reservoir for current, allowing a higher ripple current for a given size compared to other types of capacitors. Because of the high capacitance that can be achieved in a relatively small package, aluminum electrolytic capacitors are widely used in consumer electronics, such as TVs, radios, amplifiers, and other low voltage applications. Additionally, the capacitor can be used in high frequency power electronics, allowing it to serve as an effective high-frequency decoupling capacitor. It can also be used as an input and output filter in power supplies, or as a resonant capacitor in inductor-capacitor filters.Aluminum electrolytic capacitors are ideal for applications that require large capacitance and moderate temperature operation. The B43505E2687M87 aluminum electrolytic capacitor offers an elegant solution when power-related problems need to be addressed. Furthermore, when coupled with proper safeguards, these capacitors can operate reliably and help reduce oxide-layer breakdown in the process.
