Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are passive components that consist of two conducting materials, an anode and a cathode, which are separated by an insulating electrolyte layer. These components are used in many electrical and electronic circuits, such as switching power supplies, DC/DC converters, audio amplifiers, inverters, industrial control systems, RF and microwave systems, automotive applications, and power supplies for computers and military and aerospace systems.

475CKE200M Application Field and Working Principle

The 475CKE200M is an aluminum electrolytic capacitor that is designed for use in high frequency, high voltage power supplies. It is capable of withstanding operating voltages up to 150 Volts DC and is rated for continuous operation up to 50 Celsius. The capacitor has an extremely low equivalent series resistance (ESR) of 2 Ohms and a high ripple current rating.

The working principle of the 475CKE200M aluminum electrolytic capacitor is based on the idea of using two thin layers of metal foil separated by an electrolyte solution. One layer functions as the anode and the other layer is the cathode. When a voltage is applied to the capacitor, ions in the electrolyte solution are attracted to one layer or the other, depending on the polarity of the voltage. This creates an electric field between the two layers, and the magnitude of this electric field is directly proportional to the applied voltage.

The resulting electric field stores energy in the form of static charge on the capacitor. As the applied voltage increases, the strength of the electric field also increases, thus increasing the capacitance. The 475CKE200M also features a long life expectancy, with a rated life of 10,000 hours at 48 Volts DC.

The 475CKE200M aluminum electrolytic capacitor is a highly reliable, low cost solution for various high frequency, high voltage power supply applications. Its low ESR and high ripple current ratings make it ideal for applications requiring a low-voltage, high-current solution. The long life expectancy also makes it a good choice for applications where the capacitor will be subjected to frequent cycling or high temperatures.
