Aluminum electrolytic capacitors are broadly used in many different applications. The 400VXS270MEFC30X35 is one of the most popular types of such components. In this article, we are going to discuss what its application fields and working principle are.

Applications

The 400VXS270MEFC30X35 is a radial leaded aluminum electrolytic capacitor with a wide range of applications. Commonly, it is used in applications that require a high capacitance, very low equivalent series resistance (ESR) and good ripple current handling capacity, such as:

• Power supplies and SMPSs
• Electronic circuits and high-end audio equipment
• Frequency converters
• Proprietary switching/renewable energy circuits
• Any kind of DC-to-DC conversion

Working Principle

An aluminum electrolytic capacitor consists of two metallic plates immersed in a liquid electrolyte. The liquid electrolyte serves as the dielectric in between the two plates, allowing the device to build up a large amount of capacitance. Capacitance is measured in Farads, and with the 400VXS270MEFC30X35, it can range from 0.067 µF to 680 µF.

As current flows through the capacitor, the plates become positively charged when electrons move from the negative plate to the positive one. This builds up a voltage, which is known as the electrolytic potential. This potential can be up to 400 volts, making it suitable for very high-voltage applications.

The electrolytic potential is measured in volts and the most common values for the 400VXS270MEFC30X35 are 400V, 350V, and 250V. As is the case with any other capacitor, the higher the voltage, the higher the capacitance.

The advantage of using aluminum electrolytic capacitors is that they have very low equivalent series resistance (ESR), meaning that they can easily handle high voltage and current. Additionally, their long lifetime results in reliable performance over many years.

Conclusion

The 400VXS270MEFC30X35 aluminum electrolytic capacitor is a high-performance component for a variety of applications. Thanks to its high capacitance and low ESR values, it is well suited for applications such as power supplies, electronic circuits, frequency converters, and DC-to-DC conversion. Moreover, its long lifetime ensures that it can provide reliable performance over many years.
