Aluminum electrolytic capacitors are the most widely used form of capacitor in consumer applications. They are energy-storing elements which are used in a variety of consumer, industrial, and military applications. The particular type of aluminum electrolytic capacitor discussed in this article is the 200MXG680MEFCSN30X25. It is a Snap-In style capacitor, with an Assurance Double-Sided Contact design, to ensure that the entire capacitor body is always soldered to the circuit board when mounted.

Structure of 200MXG680MEFCSN30X25

The 200MXG680MEFCSN30X25 capacitor has a cylindrical shape, with its length measuring about 72 millimeters and its diameter being 30 millimeters. It is rated to operate in a temperature range of -40°C to +125°C, and starting at its outermost layer is made up of a phenolic resin insulation sleeve, which is inside a plastic sleeve with a luminescent tri-metal coating. This coating is used to provide a measure of electrical insulation and user protection from potentially dangerous electric fields that resulting from its high operating voltages. The outside of the plastic casing is then painted a bright red, to signify its high voltage capabilities.

At the heart of the capacitor is an anode layer, which is formed by electroplating aluminum on both sides of its terminal leads. Between the anode and the terminal leads is a cathode layer which consists of manganese dioxide. A gauze layer separates the anode and cathode layers, and it serves to hold the electrolyte, which is a mixture of organic and aqueous solvents such as ethylene glycol and sulfuric acid. The electrolyte supplies ions to the system to aid in electrical charge transfer.

200MXG680MEFCSN30X25 Application Fields and Working Principle

The 200MXG680MEFCSN30X25 capacitor is often used in applications that require high capacitor densities, such as in electrical power supplies, motor control circuits, and battery back-up systems. It is also suitable for use in automotive, aerospace, and medical applications due to its high temperature and voltage ratings.

The capacitance of aluminum electrolytic capacitors is determined by the surface area of the aluminum oxide layer between the two electrodes, which increases with a larger anode area. The most common value for the 200MXG680MEFCSN30X25 is 680µF, and its rated voltage is 200V. The capacitor is a non-polar device, which means that it is reversible, and the charge stored in it is determined by the value of the applied voltage and by the capacitance of the device.

The way in which it works is quite simple. When a voltage difference is applied across the terminals of the capacitor, a current will flow in the form of electrons and positively charged ions. This current causes the oxidation of aluminum, forming a thin insulating layer of aluminum oxide on both sides of the capacitor. This layer acts as a dielectric, allowing the current to loop back and forth between the two layers, building up a charge and increasing the capacitance of the device. The amount of current is determined by the voltage difference between the two terminals, and the capacitor stores that energy for later use.

The 200MXG680MEFCSN30X25 capacitor has proven to be a reliable, high-capacity capacitor for a wide range of applications, and is an essential component for many consumers, industry and military systems. Its high temperature and voltage ratings, along with its wide capacitance range, make it an ideal choice for various applications.
