EKMH201VNN331MQ25T

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized, non-solid electrolyte electrochemical capacitors with a larger capacitance per unit volume than other types of capacitors, making them especially suitable for high frequency and low current applications. EKMH201VNN331MQ25T aluminum electrolytic capacitors are a type of electromagnetic capacitor since they are also used to store energy in the form of an electrochemical reaction. These types of capacitors often incorporate a common aluminum foil as the anode and a cathode consisting of the electrolyte.

Application Field

EKMH201VNN331MQ25T aluminum electrolytic capacitors are primarily used in power supplies found in consumer electronics, particularly computer-related devices. They can be used both as a filter capacitor and as a ripple capacitor in power supplies. Other applications include motor starting, short circuit protection and snubbing applications. EKMH201VNN331MQ25T capacitors are also used in the power supplies of automotive, industrial, and light emitting diode (LED) lighting applications.

Working Principle

The working mechanism of EKMH201VNN331MQ25T aluminum electrolytic capacitors is based on two anodized aluminum foils that act as a capacitor. An anodizing process is used to deposit a thin oxide layer on the surface of the aluminum foil, creating a dielectric. Aluminum electrolytic capacitors are connected in reverse polarizing directions, with the anode having a positive polarity, and the electrolytic layer have a negative polarity. When a reverse charge is applied, the electrolyte reacts, producing an electrochemical reaction which forms a conductive oxide, thus allowing electrons to flow easily between the two electrodes. The resulting capacitance action then stores the energy in the form of an electrochemical reaction between the two electrodes and the electrolyte in the capacitor.

EKMH201VNN331MQ25T aluminum electrolytic capacitors are generally reliable and easy to use. When in use, the capacitor should be kept out of environmental extremes, such as high temperatures or damp environments, which could cause premature aging and failure. Proper ventilation and heat dissipation should always be considered, as the dielectric layers of the aluminum foil have a finite lifetime.
