Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AEC) are electronic devices that are used for storing electrical energy and are most commonly found in power supplies, motor controllers, audio equipment, bridge circuits, and automotive electronics. They work by applying a DC voltage to two aluminum plates separated by a dielectric layer that acts as an electrolyte, allowing electrical energy to be stored in capacitors.

The B43455C4478M aluminum electrolytic capacitor is an extremely popular and widely used component in the electronics industry. It offers excellent performance, reliability, and low leakage current, making it a suitable choice for a wide range of applications. This capacitor has a temperature range of -25˚C to +105˚C, and its dielectric layer is made from the 33A series aluminum electrolyte that offers superior reliability and lifetime.

The B43455C4478M is capable of operating at up to 10VAC, with a maximum capacitance of 22,000µF. It has an extremely low leakage current of just 1 µA, making it suitable for use in noise free circuits and sensitive electronic designs. In addition, it has an insulation resistance of more than 100MΩ, which ensures its high reliability in applications that require long-term operation at temperature range from -25˚C to +105˚C.

The B43455C4478M is most commonly used as a power supply capacitor, or as an energy storage device in electronic circuits, particularly in switch-mode power supplies. It is also suitable for use in automotive and audio applications, as it can withstand the vibrations of heavy duty engines and high frequencies of musical instruments. In addition, it is used in bridge circuits, voltage regulators, and systems that require low leakage current for optimal performance.

The B43455C4478M aluminum electrolytic capacitor works by changing the electrical conductivity of an aluminum plate when a voltage is applied. This causes rapid movement of electrons between the aluminum plates and the surrounding electrolyte, resulting in the buildup of electrical charges in the capacitor. As the capacitor becomes energized, it accumulates and stores energy, ready for release when the voltage is discharged.

The B43455C4478M aluminum electrolytic capacitor offers superior performance, reliability, and low leakage current, making it an ideal choice for a wide range of applications. Its excellent temperature range and long-term reliability make it especially suitable for audio, automotive, and power supply applications. Moreover, its low leakage current makes it suitable for noise-free circuits and sensitive electronic designs.
