ALF40G472KP250

Aluminum electrolytic capacitors are commonly used in a wide array of electronic applications. The ALF40G472KP250 is a robust and reliable aluminum electrolytic capacitor that finds a multitude of uses, ranging from power supply decoupling to voltage filtering. This article will take a closer look at the application fields and working principle of the ALF40G472KP250.

Application Field: The ALF40G472KP250 is a radial- Lead, non-polarized, aluminum electrolytic capacitor with a surge rating of 350V DC and capacitance of 4.7µF. Due to its high capacity and capability to handle high transient voltages, the ALF40G472KP250 is particularly well suited to high-frequency circuits like switch-mode power supplies and inverters. Possible uses also include battery backup applications, line noise suppression, and seed-filtering in telecommunications. When it comes to applications requiring enhanced temperature stability or endurance, the ALF40G472KP250 is also a good option.

Working Principle: The ALF40G472KP250 capacitor is composed of two aluminum foil electrodes with an acrylic oxide film on its surface. These two elements come in contact with an electrolyte, allowing an electric current to flow between them. The purpose of this design is to create an extremely high capacitance, while keeping the overall body of the capacitor small. The current flowing between the two electrodes creates electric charge, which causes a displacement of the charges stored on the electrodes. This process helps filter any noise that may be present in the system. This is the electric double layer capacitor’s working principle.

Conclusion: The ALF40G472KP250 is a robust and reliable aluminum electrolytic capacitor. It has a high capacitance and is able to handle high transient voltages, making it suitable for high-frequency circuits. It can also be used in applications that require enhanced temperature stability or endurance. The working principle of the ALF40G472KP250 is simple, yet effective. It is composed of two aluminum foil electrodes with an acrylic oxide film on its surface, and an electrolyte that helps create an electric current between the two electrodes. This electric current helps filter any noise present in the system.
