SKR47M400ST

Aluminum electrolytic capacitors are widely used within electrical and electronic systems for applications such as pulsed power conditioning, stabilizing gate pulses in thyristor circuits, and for energy storage. The SKR47M400ST aluminum electrolytic capacitor is a specific type of capacitor that has been designed to provide improved performance in some applications. This article will discuss the applications of the SKR47M400ST and its working principle.

The SKR47M400ST has been designed to provide higher ripple current ratings and higher capacitance-to-volume ratios than traditional aluminum electrolytic capacitors. This makes it ideal for use in applications that require tight tolerance, such as pulse power supplies and pulsed gate drive circuits. It is also suitable for use in start/stop operations due to its rapid charge/discharge ability. They also feature low ESR and ESL values, making them suitable for use in high-frequency or high-temperature applications.

In addition to its high performance capabilities, the SKR47M400ST also offers excellent stability characteristics. Its aluminum electrolyte provides superior stability over wide temperature ranges and long life over 5,000 hours. The high purity aluminum electrolyte also enhances the stability of the capacitor, reducing the risk of polarization or reddening effects. The SKR47M400ST also features a low tan δ(delta) value, meaning that it is highly resistant to losses caused by dielectric absorption.

The working principle of the SKR47M400ST is based on the well-known classic electrolytic capacitor. The capacitor utilizes a separator filled with an electrolyte between two metal plates. This separator is made of highly conductive material, such as aluminum foil, which allows electric current to flow between the two metal plates. As electric charge flows into the capacitor, a voltage is applied across the two plates, creating an electric field. This field creates an opposite electric field in the separator, which permits the electrons to migrate across the surface of the metal plates.

As the electric charge accumulates on the metal plates, the charge at the surface builds up until it eventually produces an electric potential difference between the two plates. This potential difference is referred to as the capacitance and is measured in Farads. The higher the capacitance, the more energy is stored in the capacitor. The SKR47M400ST uses a special type of electro-chemical electrolyte, which provides the highest capacitance-to-volume ratios.

In summary, the SKR47M400ST is a specific type of aluminum electrolytic capacitor that offers improved performance, stability, and endurance compared to traditional aluminum electrolytic capacitors. It is suitable for use in applications that require tight tolerance and high ripple currents. Its aluminum electrolyte ensures stability over wide temperature ranges and provides superior endurance and low-loss capabilities. The SKR47M400ST is a great choice for use in pulsed power applications and start/stop operations due to its superior charge/discharge characteristics.
