EKZN250ELL472MM25S

Aluminum electrolytic capacitors are a popular type of capacitor, and the model EKZN250ELL472MM25S is one type of them. They feature a long lifespan and durability, making them a go-to choice for a variety of applications. This article will discuss the application field and working principle of the EKZN250ELL472MM25S.

Application Field

Aluminum electrolytic capacitors like the EKZN250ELL472MM25S are typically used for applications that require high capacitance and a long working lifespan. Commonly, the EKZN250ELL472MM25S is employed in the fields of automotive electronics, radio and communication systems, high-volume power supply design and other higher-end electronic product design. Further, these capacitors can be used to filter out ripple, block DC, store energy, deliver amplitude and phase modulation, as well as providing other waveforms.

Working Principle

The basic working principle of aluminum electrolytic capacitors like the EKZN250ELL472MM25S is similar to that of other capacitors. An electric field is created between two conductive plates, and when that field is broken by an external voltage, current is able to flow through the capacitor. However, aluminum electrolytic capacitors are typically constructed with an anode, a dielectric and a cathode instead of the two conductive plates of other capacitors.

The anode of the EKZN250ELL472MM25S is an aluminum foil with etched microscopic pores. The etched surface increases the available surface area, allowing more charge to be stored. The cathode is an aluminum oxide, while the dielectric is a liquid electrolyte that helps create a better electric field. When an external voltage is added, an electric current is formed, allowing the capacitor to store energy.

Conclusion

Aluminum electrolytic capacitors are some of the most popular capacitors on the market today. The EKZN250ELL472MM25S model is no exception, with its long lifespan and compatibility with high-volume applications. This article has discussed the application field and working principle of the EKZN250ELL472MM25S, breaking down how it functions and what it is typically used for.
