Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (known as AEC) are a type of polarized capacitor that consists of two electrodes covered by an aluminum oxide dielectric and encased in a metal can filled with an electrolyte, usually a mixture of ethanol and water. AECs have the advantage of being relatively cheap to produce and can be produced with relatively high capacitance values in a small size compared to other types of capacitors.

B43504C2477M67 Application Field

The B43504C2477M67 is an AEC designed for general-purpose applications, including line by-pass, coupling, bypass, decoupling, and filtering. In line by-pass or decoupling applications, this AEC is often used to reduce the ripple and noise created by AC power supply lines or to provide energy storage to help maintain system stability in the event of an overload. This AEC can also be used in parallel configurations to improve filter effectiveness, or used in series configurations for high frequency snubbing.

B43504C2477M67 Working Principle

The working principle behind an AEC is relatively simple. When a current is applied across the two plates of the capacitor, the aluminum plate is anodic and the electrolyte is cathodic, and the oxide is the dielectric. The current causes the oxide layer to slowly dissolve on the anodic plate, while simultaneously regenerating on the cathodic plate. This phenomenon forms an electrical field across the dielectric layer, generating the capacitance value. AECs are typically able to hold a higher voltage than other types of capacitors and can usually handle more current and frequencies.

Conclusion

The B43504C2477M67 is an AEC designed for general-purpose applications, such as line by-pass, coupling, bypass, decoupling, and filtering. It can be used in parallel and series configurations in order to improve effectiveness. The working principle behind AECs involves the generation of electrical field across the oxide layer, forming the capacitance value. AECs are typically able to hold a higher voltage than other types of capacitors and can usually handle more current and frequencies.
