Aluminum - polymer capacitors, such as the 476ULR025MFF, are an ideal choice for applications requiring a highly durable and reliable capacitor. They combine the benefits of both aluminum electrolytic and polymer capacitors, offering outstanding performance in a variety of setups. In this article, we will explore the application field and working principle of the 476ULR025MFF.

The 476ULR025MFF is a surface mount aluminum–polymer capacitor that is designed for use in power supplies, in mobile phones and other portable instruments, and on main boards of commercial motherboards. It has a long service life and is highly reliable, due to its low leakage current and high dielectric strength. The capacitor has a low equivalent series resistance (ESR), and is capable of operating in high-frequency applications. Because of its small size, the 476ULR025MFF can be easily mounted on a variety of board types, making it ideal for use in a wide range of applications.

The working principle of the 476ULR025MFF aluminum–polymer capacitor is based on the storage of electrical energy within the capacitor element. The aluminum–polymer construction includes a very thin layer of aluminum foil and a dielectric polymer. When voltage is applied across the capacitor, a positively charged layer is formed on the surface of the aluminum, which creates a strong electric field. This electric field causes the polarization of the dielectric polymer, resulting in a charge imbalance that can store energy.

The 476ULR025MFF capacitor offers several advantages compared to other types of capacitors. It has a very low equivalent series resistance (ESR), and a high voltage capability, which means it can be used in high-frequency applications. It also has a very accurate capacitance value, and is highly stable over time. The 476ULR025MFF capacitor is highly reliable, and its long service life makes it ideal for a variety of applications.

The 476ULR025MFF aluminum–polymer capacitor is an ideal choice for many applications because of its performance, reliability, and longevity. It is an excellent option for power supplies, onboard batteries, and a wide range of portable instruments. Additionally, because of its small size, it is easy to mount on a variety of board types, making it an ideal choice for a wide range of applications.
