Aluminum electrolytic capacitors are a type of capacitors which make use of an anode made of a pure aluminum foil with an etched surface, a electrolyte which acts as the cathode, and separators which are impermeable to the electrolyte. They are widely employed in various applications such as AC line-filter applications, RF signal-coupling applications, motor controllers and in numerous other DC-blocking, AC-signal-coupling and AC-line-filter applications.

The E81D251VNN331MQ35C is an aluminum electrolytic capacitor which is designed for use in high voltage AC systems and DC supply circuits. The capacitor utilizes a combination of a solid-electrolyte anode, an epoxy resin impregnated electrolyte and metalized foil used as the separator in order to provide capability for handling high-voltage systems, and thus is frequently used in the construction of large motor controllers and motor-control circuits. Aside from that, it is also utilized in some common AC power-line filtering applications as well.

The E81D251VNN331MQ35C capacitor features a cylindrical construction and is composed of an anode foil composed of an etched pattern which is then connected to axial leads. An electrolyte impregnated separator is also used, with an insulating paper colloid used as the separator material between the anode foil and the electrolyte. The dielectric material, which is epoxy resin, and the lead-terminal connections are then encapsulated within a polypropylene/polycarbonate plastic housing. The E81D251VNN331MQ35C capacitor has the capacity of handling up to 330V of AC power and is employed mainly for larger motors and AC power-line filtering applications.

The working principle of the E81D251VNN331MQ35C capacitor is based upon the concept of dielectric absorption. The capacitor works by creating an electric field between two conductors that store electrical energy in the form of an electrostatic field. This electrostatic field generates an electric current in the anode material of the capacitor and an equal and opposite current in the electrolyte. The current generated in the electrolyte is absorbed by the electrolyte due to its high dielectric absorption and then stored in the capacitor as an electromagnetic field.

By utilizing this dielectric absorption principle, the E81D251VNN331MQ35C capacitor can effectively store and release electrical energy as required by the application for which it is used. Its design makes it ideal for use in larger motor controllers, AC power-line filtering applications, and for other DC-blocking, AC-signal-coupling and AC-line-filter applications. In addition, due to its construction, it is also capable of withstanding the high-voltage systems for which it is utilized.
