EKMS181VSN391MP25S

Aluminum electrolytic capacitors, or electrolytic capacitors, are polarized, radial lead, cylindrical electrical capacitors whose anode (positive end) is composed of an aluminum oxide layer and its cathode (negative end) is composed of aluminum. This type of capacitor is widely used in a variety of electrical and electronic circuits. EKMS181VSN391MP25S is an example of an aluminum electrolytic capacitor used in telecommunication equipment and other such applications. This section will take a closer look at the application fields and working principles of this capacitor type.

Application Field of EKMS181VSN391MP25S

EKMS181VSN391MP25S products are aluminum electrolytic capacitors developed by KEMET & Sanyo, and are widely used in telecommunications equipment including MRF series DC/DC converters, voltage regulators, heater controllers, and other similar electronic equipment.

EKMS181VSN391MP25S capacitors have a wide range of applications, such as interference suppression, smoothing of ripple voltage, and filtering of noise generated by power supply. These capacitors are also suitable for use in audio equipment, such as audio transformers, preamps, and equalizers, and can also be used in inverters and motor drive circuits, both of which require very low impedance.

Working Principle of EKMS181VSN391MP25S

The working principle of EKMS181VSN391MP25S aluminum electrolytic capacitors is based on the principle that an electrical current will be generated on the surface of a dielectric, or insulator, when it is exposed to an electric field. This phenomenon is called electric double layer effect, and this effect is the basis of electrochemical capacitors. In this case, the dielectric is the aluminum oxide layer that is the anode of the capacitor.

When an electric potential is applied to the capacitor, electrons move through the anode to the cathode to form a double layer of electrons. The density of this double layer increases with the applied voltage, increasing the capacitance and allowing for the storage of greater amounts of electrical energy. As the capacitance increases, the voltage across the capacitor will decrease, as it does in other types of electrical capacitors. Once the voltage is removed, the capacitance will gradually return to its original state.

Conclusion

EKMS181VSN391MP25S is an example of an aluminum electrolytic capacitor type used in telecommunications equipment and other such applications. This type of capacitor is based on the effect of the electric double layer, and is widely used for its ability to store and release large amounts of electrical energy. In addition, EKMS181VSN391MP25S capacitors are also suitable for use in inverters, motor drives, audio equipment, and other similar applications.
