Aluminum electrolytic capacitors, also called aluminum electrolytic, are electrochemical capacitors that use aluminum oxide as a dielectric medium. They are one of the most widely used capacitors in the electronics industry because of their reliability, low cost and very high capacitance values. The B43858C9475M000 is an aluminum electrolytic capacitor designed specifically for the electronics industry.

The B43858C9475M000 aluminum electrolytic capacitor is an SMD capacitor with a maximum capacitance value of 475μF and a rated voltage of 4V. It is a surface mount aluminum electrolytic capacitor with a maximum ripple current of 2.8A at 50Hz. It has a wide operating temperature range of -55°C to +125°C and a long-term leakage current of 1.5%. It is also RoHS compliant and UL recognized.

This aluminum electrolytic capacitor is mainly used in automotive, lighting, LED, power conversion and consumer electronics applications. It is designed to provide long-term, reliable operation in high-temperature and corrosive environments. The high capacitance, low ESR and ESD ratings make this capacitor suitable for use in high-frequency power conversion. The design is also well suited for pulse-load applications and provides a good compromise between longevity and electrical performance under severe environmental conditions.

The working principle of the B43858C9475M000 aluminum electrolytic capacitor is very simple. It uses an aluminum foil and an electrolyte to create a capacitance. The aluminum foil is the anode and is etched into a porous surface. The electrolyte is then applied to the porous surface and provides the electrical connection between the anode and the cathode. As a voltage is applied, the electrolyte ionizes and a very thin and porous layer of aluminum hydroxide is formed. This layer is called the capacitance dielectric layer. The capacitance of the capacitor depends on the porosity of the anode, the electrolyte used and the applied voltage.

The B43858C9475M000 is a high-temperature SMD aluminum electrolytic capacitor that provides reliable performance and long-term stability. It is designed for use in automotive, lighting, LED, power conversion and consumer electronics applications. Its wide operating temperature range and high capacitance, low ESR and ESD ratings make it suitable for use in a variety of high-frequency power conversion applications.
