The capacitor is designed with a standard radial lead and axial lead construction, allowing it to be easily mounted in tight spaces. It is also designed to be physically robust and high in capacitance stability, allowing it to be used in demanding applications.

Working Principle

The 420QXW39MEFC10X35 is an aluminum electrolytic capacitor, which is composed of two electrodes separated by an electrolyte. The electrodes of the capacitor are made from aluminum foil which is etched into a thin and narrow pattern. The electrolyte, which is usually a liquid or a gel, acts as an insulator between the two electrodes, preventing electrical current from passing through.

When the capacitor is subjected to an alternating current, the flow of charge is established between the two electrodes. This causes electrical charges to accumulate in the capacitor, creating a potential difference across the capacitors’ terminals. This potential difference, also known as the capacitors’ voltage, is what makes it a useful component in electronic circuits.

Aluminum electrolytic capacitors are known for their high capacitance, low loss, and low equivalent series resistance (ESR). This makes them ideal for use in applications such as power factor correction, electronic filters, DC-DC converters, and other power management applications.

Conclusion

The 420QXW39MEFC10X35 is an aluminum electrolytic capacitor with a wide range of applications and excellent performance. It is designed to be physically robust and high in capacitance stability, making it suitable for use in demanding applications. It is also designed with a maximum voltage of 420 VDC, making it suitable for applications with a high voltage, such as motor control, power supplies, lighting ballasts, and other power management applications.

The working principle of aluminum electrolytic capacitors is based on the accumulation of electrical charge between two electrodes separated by an electrolyte. When the capacitor is subjected to an alternating current, the flow of charge is established between the two electrodes, creating a potential difference across the capacitors’ terminals. This potential difference is what makes aluminum electrolytic capacitors useful in electronic circuits.
