Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various industries because of their various advantages, such as high capacitance, low equivalent series resistance, and long service life. Their wide application fields include applications such as signal filtering and energy storage, etc.

B41231B5229M000 is an aluminum electrolytic capacitor with high performance and reliability. It has a capacitance of 220μF and a working voltage of 2.5V. Moreover, its operating temperature is -40~+105℃ and its mounting type is radial lead.

Working Principle

B41231B5229M000 aluminum electrolytic capacitors are composed of anode sheet, dielectric layer and cathode tube. The metal anode sheets are wound up into a roll form and are insulated with a dielectric layer. The cathode tube is placed inside the anode roll and electrolyte is filled in the tube. Thus, a pair of plates can be formed on the inside and outside of the anode roll. When DC voltage is applied to the capacitor, electric break-down occurs between the anode and cathode, forming a capacitor. The capacitance depends on the size and surface area of the anode sheets.

Application Fields

Due to their relatively large capacitance, B41231B5229M000 aluminum electrolytic capacitors can be widely used for signal coupling, energy storage, low-frequency bypass, high-frequency cutoff, and filter. Additionally, they are also used in motor drivers, inverters, and circuits with onboard voltage regulators.

In signal coupling applications, due to its low charge leakage, B41231B5229M000 aluminum electrolytic capacitor can be used to prevent the superposition of related signals and the interference between different signals. Moreover, they can also be used in energy storage application to filter any high frequency voltage ripple.

In power supplying application, B41231B5229M000 aluminum electrolytic capacitors are used in motor drivers, inverters, and circuits with onboard voltage regulators to achieve efficient circuit control. In these applications, the capacitors reduce current, compensate for voltage fluctuations, and help to avoid interference with other signals.

Thus, B41231B5229M000 aluminum electrolytic capacitors are used in a variety of applications due to their reliability and wide operational temperature range. In addition, they can also be used in low-frequency bypass, high-frequency cutoff, and filter applications.
