Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are electrochemical capacitors which use anodized aluminum foils, separated by a dielectric, as their energy storage medium. AECs have been around since the late nineteenth century, but have become more popular in the last decade as they have become a more efficient and reliable solution for applications requiring high energy storage. Generally, AECs are the best choice for projects where the capacitor values are high.The specific model of AEC in question is the EKMQ401VSN331MR35S. Though this model is only one of the many types of AECs in the market, its features and design settings make it an ideal choice for a variety of applications. This article will discuss the application field and working principles of the EKMQ401VSN331MR35S in detail, and how this specific AEC model fits different types of applications.

Design Features and Specifications of the EKMQ401VSN331MR35S

The capacitance of the EKMQ401VSN331MR35S is 4.0 uF, its rated voltage is 160 VDC, and its operating temperature range is -40 to +105°C. Its case is made of resin, which is both flame-retardant and self-extinguishing, and its size is 45 x 20 mm. Additionally, the AEC is equipped with a high luminance luminous window and a convenient mounting hole, allowing for easy installation inside a piece of equipment. Furthermore, the EKMQ401VSN331MR35S makes use of an “electrolyte-filled” dielectric, which helps to maximize its energy storage capability. This dielectric also ensures that the AEC is highly durable and reliable.

Application Field and Working Principle of the EKMQ401VSN331MR35S

The EKMQ401VSN331MR35S is suitable for use in a wide variety of applications. Its high capacity and wide operating temperature range make it an ideal choice for power supplies, inverters, switching DC/DC converters, and many other power electronic circuits. Additionally, its low ESR ratings make it ideal for applications requiring high frequency switching and high current ripple. As with all electrolytic capacitors, the EKMQ401VSN331MR35S works using electrochemical force. Two aluminum foils are anodized, separated by a dielectric membrane. The aluminum foils are connected to a positive and negative terminal, which is then connected to a power source. When a voltage is applied, the electric field passes through the dielectric membrane. This creates an opposite electric field on the other side of the membrane, which causes the positive and negative charges to attract and form a capacitance. This capacitance enables the device to store electrical energy, allowing it to be released rapidly when needed.

Conclusion

The EKMQ401VSN331MR35S aluminum electrolytic capacitor is a highly versatile component that can be used in a variety of applications. Its wide operating temperature range and high capacity make it well suited for power supplies, inverters, and other power electronic circuits. Additionally, its low ESR ratings enable it to handle high frequency switching and high current ripple. Finally, it is made with a flame-retardant and self-extinguishing case, ensuring reliable and safe operation.
