ESMH401VNN101MQ25W

Aluminum electrolytic capacitors (AECs) are electrochemical capacitors with a larger capacitance than other types of capacitors. They are widely used in many applications, such as for power supplies, audio systems, medical equipment, consumer electronics, automotive applications, and various industrial applications. The ESMH401VNN101MQ25W is a product of this type of capacitor. This article will discuss the application field and working principle of the ESMH401VNN101MQ25W.

Application Field

The ESMH401VNN101MQ25W is a single-ended electrolytic capacitor designed for use in high- frequency DC-DC converters and other high-speed switching circuits. It is rated for a maximum voltage of 1000V, and it has a very wide temperature range and long life span. This makes it well suited for use in applications where the temperature and current fluctuations are significant. The ESMH401VNN101MQ25W is also suitable for use in applications such as powerline filtering, switching power supplies, telecommunications, electrostatic discharge protection circuits, and protection and compensation of other high-frequency switching elements.

Working Principle

The ESMH401VNN101MQ25W is an aluminum electrolytic capacitor that consists of an aluminum oxide layer that acts as the dielectric material. This layer is formed when aluminum electrodes are electrochemically etched. The etched aluminum is then separated by an electrolyte solution, which further increases the capacitance. The electrolyte solution also serves to dissolve and spread any contaminates that may occur during the manufacturing process.

The key feature of the ESMH401VNN101MQ25W is its conductive polymer technology. This technology utilizes a phosphoric acid solution as the electrolyte instead of traditional electrolytes. This phosphoric acid solution greatly improves the life and capacitance of the capacitor. Additionally, the conductive polymer technology helps to reduce ESR and ripple current, thereby making the ESMH401VNN101MQ25W ideal for high-frequency applications.

The ESMH401VNN101MQ25W is a highly reliable aluminum electrolytic capacitor. Its long life span, wide temperature range, and high capacitance make it an ideal choice for many applications. It is especially suitable for use in high-frequency DC-DC converters and other high-speed switching circuits.
