Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are capacitors with the largest capacitance per unit volume at present. They use an aluminum oxide film on the surface of an electrolytic sheet as the dielectric. The capacitance of aluminum electrolytic capacitors changes significantly with the frequency of the signal passing through the capacitor. At higher frequencies, the capacitance of the aluminum electrolytic capacitor can be significantly reduced, sometimes as little as 1/10 of the value at low frequency. Because of these characteristics, aluminum electrolytic capacitors are mostly used to filter signals in audio, video, and power supplies.

The aluminum electrolytic capacitor model B43505A5337M60 is a radial leaded aluminum capacitor with long life and high volumetric efficiency, made of aluminum foil, electrolyte and anodized aluminum oxide sheets. It can withstand high ripple currents, has a broad operating temperature range of -55 to +105°C, and a miniaturized size, providing a wide range of applications in a variety of consumer and industrial products.

The working principle of aluminum electrolytic capacitors is based on Faraday’s Law. During the electrolytic reaction, the aluminum surface is oxidized to form an oxide layer. The oxide layer is electrically insulating, which results in a dielectric. An electric field is applied between the positive pole of the capacitor and the negative electrode, forming a charge separation.

The B43505A5337M60 aluminum electrolytic capacitor is particularly suitable for several important application fields. It is widely used in DC-DC converters, buck and boost converters, power inverters and switched-mode power supplies. It is also used in the audio and instrumentation industries as an AC decoupling filter for signal attenuation and harmonic elimination. The capacitor is also used in automotive, industrial, home appliance and computer peripheral electronic equipment.

In conclusion, the B43505A5337M60 aluminum electrolytic capacitor is highly suitable for applications in a variety of industries, due to its long life, high volumetric efficiency, wide operating temperature range and ability to withstand high ripple currents. Its working principle is based on Faraday’s Law, where an oxide layer is created from the reaction between the aluminum surface and an electrolyte solution, resulting in a charge separation.
