Working Principle

Aluminum electrolytic capacitors work by creating an electric field between two conductors, one positively and the other negatively charged. The positive plate, also known as the anode, is made of aluminum and acts as the static conductor in the capacitor. This plate is treated with an oxide film, which functions as a dielectric, creating a barrier between the two plates. The negative plate, known as the cathode, is made of a porous material and is immersed in an electrolyte.

When a voltage is applied to the aluminum electrolytic capacitor, a current flows between the two plates. This current creates an electrostatic field that causes the positively charged anode to be attracted to the negatively charged cathode, causing electrons to flow between the two plates. This process causes the capacitor to store electric energy and release it when voltage is applied to it.

Conclusion

The E91F421VSN271MR50T is a type of polarized aluminum electrolytic capacitor which improves current carrying capabilities as well as a high voltage rating and annular corrugated foil construction for increased capacitance. This capacitor is commonly used in high voltage DC power supplies, A/C supplies, battery powered DC power supplies, and for circuits with high voltage AC or DC ripple current due to its robust construction, high voltage rating, and wide capacitance range, making it a versatile and reliable choice for a variety of electronic applications.
