Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are components that store electrical energy as the result of a static electric charge. They are commonly used in many electronic circuits for rectification, coupling, and decoupling of signal frequencies. This type of component is made by forming an aluminum foil electrode with a thin oxide layer etched onto the metal surface. This oxide layer serves as a dielectric and allows for the storage of electric charge between two metal plates. This type of capacitor is the most commonplace general-purpose capacitor in use today due to its combination of size, capacitance, voltage, temperature co-efficiency, and durability.

EKMR401VSN271MR25S Application Field and Working Principle

The EKMR401VSN271MR25S is a type of aluminum electrolytic capacitor that has a rated voltage of 125VDC, rated capacitance of 270 microfarads, and a temperature coefficient of -30%. Its operating temperature range is between -55°C and 105°C. This type of capacitor is designed to provide stable electrical characteristics under temperature changes and to minimize the temperature induced losses usually seen with lower-end electrolytic capacitors.

Its wide operating temperature range makes it well-suited for rugged, industrial and medical applications.

The EKMR401VSN271MR25S employs an anode, or positively charged plate made from aluminum foil. This plate is then etched with a thin dielectric oxide layer. This layer serves as an insulator, allowing for electrons to be stored between the two metal plates. This is caused by the creation of an electric field. Current is easily transferred across the capacitor when a voltage is applied to it, allowing for the storage of electrical charge.

In conclusion, the EKMR401VSN271MR25S is an aluminum electrolytic capacitor with many practical applications. It is most often used in audio applications due to its reliability and temperature stability. Additionally, it is a good choice for pulse signal filtering, buffer, and low temperature drift applications. Its anode is made of etched aluminum with a thin oxide layer that serves as a dielectric, allowing for the storage of electric charge.
