Aluminum Electrolytic Capacitors

50YXH680MEFC12.5X30 Application Field and Working Principle

Aluminum electrolytic capacitors are a kind of polarized capacitor which typically consists of an aluminum foil covered with a very thin layer of oxide film, with a metal rod protruding from the oxide film and a negative pin connected to the can casing used for the electrical contact. They offer high energy density, low-valued capacitance, good temperature stability, excellent frequency response, and long life expectancy in a wide range of applications including automotive, industrial, medical and consumer electronics.50YXH680MEFC12.5X30 is the model number for a type of Aluminum electrolytic capacitor produced by the company Nippon Chemi-Con. It is designed for applications like switch mode power supplies for secondary smoothing, low voltage power sources and general power supplies in electronic equipment.

Working Principle

Aluminum electrolytic capacitors are based upon the physical principles of a galvanic cell, where the oxide covered surface of the aluminum foil acts as the anode (positive terminal) and a metal rod, or lead, is attached to the oxide film serving as the cathode (negative terminal). The capacitance of the capacitor is determined by the area of the oxide film, and it typically ranges from 1µF to 10,000µF.When a voltage is applied to the capacitor, an electrical current passes through the oxide film and reacts with the aluminum film to form an electrolyte between the anode and the cathode. This electrolyte acts as a separator, keeping the two electrodes separated and preventing a short-circuit from taking place. The result is a large space charge which stores energy.

Application Field

50YXH680MEFC12.5X30 can be used for a wide range of applications such as: 1.Smoothing of output voltage and current in switch-mode power supplies. 2.Improving efficiency in DC-DC converters. 3.Backup for micro-controllers. 4.Pulsed power supplies. 5.Timing and delay circuits. 6.Voltage level converters. 7.Signal conditioning. 8.Audio circuits. 9.Base Station Systems. 10.Robotics.

Conclusion

In conclusion, the 50YXH680MEFC12.5X30 model of Aluminum Electrolytic Capacitor produced by the company Nippon Chemi-Con offers many advantages over other capacitors due to its compact size, high energy density, low-valued capacitance, good temperature stability, excellent frequency response, and long life expectancy. It can be used in a wide range of applications, making it very useful for engineers and designers.
