Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy-storing components used for decoupling, filtering, and buffering in electronic systems. These components are widely used in various digital circuits and non-digital circuits. In the electronic industry, aluminum electrolytic capacitors represent one of the most import components within a system.

AFC476M35E16T-F is a series of aluminum electrolytic capacitors produced by Amphenol. This series is designed with an impedance-low ESR (Equivalent Series Resistance). It is specially designed for high-frequency applications and offers a maximum ripple current rate of 16A and a capacitance range from 4.7 to 470microfarads. The AFC476M35E16T-F series is a cost-effective solution to improve power integrity in your system.

Applications of the AFC476M35E16T-F series include high-current and high-frequency applications such as power supplies, automotive, and aerospace applications. The AFC476M35E16T-F series is designed to provide a high ripple current and low ESR performance for high temperature and high-frequency environments. With its high temperature durability, the AFC476M35E16T-F series is a perfect choice for high-temperature, high-power applications.

To understand the working principle of the AFC476M35E16T-F series, we need to take a closer look at how traditional aluminum electrolytic capacitors work. Aluminum electrolytic capacitors contain two metallic plates separated by a dielectric layer. The negative plate is a layer of pure aluminum, and the positive plate is a layer of aluminum oxide. The positive and negative plates are connected to a pair of terminals, with the positive terminal connected to a junction that is exposed to the exterior. When a voltage is applied to the capacitor, the positive and negative plates will draw electrons from the electrolyte solution and establish a potential field that allows current to flow.

The AFC476M35E16T-F series adds an additional feature to the traditional aluminum electrolytic capacitor. A sintered end seal is located at the negative terminal of the capacitor. The end seal serves to effectively regulate the current and voltage applied to the capacitor, and it also provides a mechanism to minimize the effects of dielectric absorption. The end seal also improves the capacitor’s ability to keep its capacitance constant and reduces the ESR.

This sintered end seal also improves the capacitor’s capacitance and its ability to respond to rapid changes in voltage. It helps to reduce the voltage spike and ESR experienced at high frequencies. The end seal also helps to reduce the power dissipation that would normally occur at high temperatures. The AFC476M35E16T-F series has a rated temperature range of -55C to +125C.

In conclusion, the AFC476M35E16T-F series is a cost-effective and reliable solution for various applications, especially in high-current and high-frequency settings. The sintered end seal advances the design of aluminum electrolytic capacitors by adding an additional feature that reduces the ESR, voltage spike, and power dissipation. This makes the AFC476M35E16T-F series a very desirable choice for high-temperature, high-power applications.
