Aluminum Electrolytic Capacitors – B43858A9476M000 Application Field and Working Principle

Aluminum electrolytic capacitors are one of the most widely used type of capacitors in the industrial and consumer electronics world and come in a variety of shapes, sizes and constructions. The B43858A9476M000 aluminum electrolytic capacitor Series is a robust, self-healing, and reliable capacitive element for applications requiring high capacity and low costs with long-term reliability.

Overview of B43858A9476M000 Aluminum Electrolytic Capacitors

B43858A9476M000 aluminum electrolytic capacitors are high capacitance, low ESR solid electrolyte capacitors designed for a wide range of harsh environment applications – from ambient temperature operation up to 105 °C. They are manufactured using a unique technology which harnesses the self-forming properties of aluminum oxide and the thermal stability of electrolyte. This gives them high capacitance and low ESR values similar to that of a wet electrolyte capacitor, but with superior life expectancy and lower cost.

Types of B43858A9476M000 Aluminum Electrolytic Capacitors

B43858A9476M000 aluminum electrolytic capacitors can be used in a variety of applications including power supplies, radio frequency amplifiers, motor drives, high voltage switching, and military and aerospace applications. They come in multiple sizes with a broad range of capacitance values ranging from 47 µF to 3,300 µF, with options for radial and axial leaded packages, and with various insulation sleeve and crimp configurations. The wide range of operating temperatures, ESR ratings, and capacitance values makes the B43858A9476M000 series ideal for a wide range of demanding applications.

Operation and Working Principle

B43858A9476M000 aluminum electrolytic capacitors use a wet electrolyte but unlike other electrolytic capacitors, they do not require a fill-up port and have a much longer life expectancy. This is achieved by adding a patented material which encapsulates the electrolyte, preventing it from leaking and evaporation. This material is also highly resistant to thermal shock and chemical degradation, further extending capacitor life. The capacitor also contains an anode and a cathode formed by an etched aluminum foil that are dipped into the electrolyte.

When the capacitor is energized, positive ions move into and out of the electrolyte. This generates a current that creates a dielectric layer on the anode, leading to the formation of an electric double-layer. This dielectric layer acts like an insulation, preventing electricity from flowing freely between the anode and the cathode. The capacitor, therefore, acts like a reservoir of electrical charge, providing a stable source of energy for electronic circuits.

Advantages and Disadvantages of B43858A9476M000 Aluminum Electrolytic Capacitors

The main advantages of B43858A9476M000 aluminum electrolytic capacitors are their high capacitance, low ESR values, and longer life expectancy when compared to other types of capacitors. They also provide excellent performance in extreme environments and are cheaper than other types of capacitors with similar properties. However, they do have some drawbacks, such as their limited operating temperature range, high leakage current, and large surge currents.

Conclusion

B43858A9476M000 aluminum electrolytic capacitors offer a combination of high capacitance, low ESR values, and longer operational life, making them the preferred choice for high performance and high reliability applications in harsh environments. By harnessing the self-forming properties of aluminum oxide and the thermal stability of electrolyte, B43858A9476M000 aluminum electrolytic capacitors are designed to deliver robust and reliable operation in extreme environmental conditions.
