Aluminum electrolytic capacitors are widely used in various electronic devices and equipment. The CGS781T400V4C is an aluminum electrolytic capacitor. This article will discuss its application field and working principle.
Application Field
CGS781T400V4C is an electrolytic capacitor designed with voltage rating of 400V and capacitance of 781μF. It is a type of high-temperature cylinder electrolytic capacitor. Its broad operating temperature range of -55℃ to +105℃ and endurance up to 2000h at 105℃ makes it suitable for use in various electronic devices with high temperature requirements, including solar inverters, motor drives, safety devices, and power supplies. In addition, it is ideal for use in primary power applications where high reliability and long life expectancy are necessary.
Working Principle
CGS781T400V4C aluminum electrolytic capacitor operates on the principle that when a voltage is applied across an electrolyte solution, small charged particles called ions migrate through the solution and form a conducting path between two metal plates, also known as electrodes. These electrodes are then separated by a thin material or dielectric called the anode. This anode prevents electrons from crossing over from one electrode to another. The electrons are forced to pass through the electrolyte solution, creating an electrical current that passes between the two electrodes.
The CGS781T400V4C capacitor features a low internal resistance and is made with a double layer electrolytic system, which further enhances its electric current transferring capability. The combination of low resistance and the double layer electrolytic system enables this electrolytic capacitor to work at a higher frequency, making it suitable for use in high frequency applications such as switch mode power supplies.
The CGS781T400V4C aluminum electrolytic capacitor features an electrolyte designed with low evaporation rate and excellent chemical stability. Its electrolytic film and aluminum foil give it good corrosion resistance and a high operating accuracy. Its patented self-healing technology ensures that it can quickly self-recover and continue to operate in the event of a short circuit.
In conclusion, CGS781T400V4C aluminum electrolytic capacitor is an ideal solution for various high temperature applications, featuring a wide operating temperature range and excellent chemical stability. Its patented self-healing technology makes it suitable for primary power applications where high reliability and long life expectancy are necessary.
