Aluminum electrolytic capacitors are extremely popular and widely used in a variety of applications. The 687LMU200M2DE is a type of aluminum electrolytic capacitor which has been specifically designed for high power and high efficiency applications. This article will discuss what makes this particular aluminum electrolytic capacitor special, the various applications that it is suitable for, and its working principles.

Construction and Design Features

The 687LMU200M2DE aluminum electrolytic capacitor is a high-voltage, high-capacity device designed for use in applications where many other capacitors are not able to survive. This device features a long life with exceptional reliability and is capable of withstanding wide temperature extremes. It has also been designed with an increased ripple current capability, enabling increases in current flow without a significant reduction in lifespan.

The capacitor has a tall, cylindrical shape with a case size ranging from 18 mm to 24 mm, and is available in both **snap-in** and **screw-down** configurations. Furthermore, the device has an operating voltage of up to 400 VDC, with rated capacitance up to 10,000 uF and a ripple current rating of 2,900 mA.

Applications

The 687LMU200M2DE aluminum electrolytic capacitor can be used in a variety of applications where other capacitors are not suitable or cost effective. The device is suitable for use in high power audio systems, solar arrays, uninterruptible power supplies (UPS), motor drives, high voltage DC-DC converters, power factor correction circuits, and in industrial control systems.

The capacitor is also suitable for use in HVAC systems and in aerospace and military applications. Moreover, it is suitable for use in high-voltage/high-current crowbar circuits, in which the sudden flow of current must be controlled in order to avoid damaging components. The capacitor’s high voltage and ripple current capability makes it an ideal choice for applications which require both characteristics.

Working Principle

The 687LMU200M2DE aluminum electrolytic capacitor works by storing a large amount of energy between two sheets of conductive liquid electrolyte separated by a porous separator. The separator acts as a barrier and allows the two sides to remain insulated from one another. One side of the electrolyte is connected to the anode, while the other side is connected to the cathode.

When a voltage is applied across the anode and cathode, the electrons flow from the anode to the electrolyte and form a vibrating electric field. This vibrating electric field creates an electric charge which is stored in the capacitor. This charge is then released when the voltage is removed. The device is able to store a large amount of charge in a relatively small package, making it suitable for a variety of high power applications.

Conclusion

The 687LMU200M2DE aluminum electrolytic capacitor is a high-voltage, high-capacity device designed for use in a variety of high power applications, including audio systems, solar arrays, uninterruptible power supplies (UPS), motor drives, high voltage DC-DC converters, power factor correction circuits, and industrial control systems. It is particularly well suited for crowbar circuit applications. The capacitor works by storing a large amount of energy between two plates of conductive liquid electrolyte separated by a porous separator. This allows the device to store a large amount of charge in a relatively small package, making it an ideal choice for high power applications.
