Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are composed of two aluminum foils rolled into spirals with the separator between them soaked with electrolyte. The cathode of the aluminum electrolytic capacitor is an aluminum foil with an etched surface to form a large number of fine double-layer capacitors in parallel. The anode is formed on the outer layer of the electrolytic foil with an oxide film and acts as an "insulation". The electrode of the capacitor is separated by a semi-permeable paper sheet soaked in electrolyte.

The 315USC220MEFCSN25X25 field and working principle of aluminum electrolytic capacitors can be divided into three parts: First, the working principle of the electrolytic capacitor. The working principle of electrolytic capacitor is that under the DC drive, the anode and the cathode form an electric double-layer in the electrolyte, the electrolyte acts as an insulator, a certain potential difference is formed between the double layer, and the DC electricity is stored as electric charge in the electric double layer at both ends of the electrolyte. The working principle of electrolytic capacitor is similar to that of a general capacitor.

Second, the application field of aluminum electrolytic capacitors. Aluminum electrolytics are widely used in the electronics and electrical industry, instrument and machinery control, power control, automotive systems and other fields. They are also used for the radiating of electronic equipment, radio, television sets, computers, automatic control systems, counters, power supply filter, lighting and other products. The application field of the 315USC is mainly in power systems, and the important use is in lightning protection devices.

Third, the characteristics of the 315USC220MEFCSN25X25. This series of capacitors has a C/V value of 120%~150%, and has excellent low leakage, dielectric loss, long life and damage prevention characteristics, which makes it suitable for a wide range of applications, including high reliability systems. The working frequency is also relatively wide, up to several hundred KHz.

In conclusion, the 315USC220MEFCSN25X25 is an aluminum electrolytic capacitor with excellent performance and has a wide range of applications. The working principle of this capacitor is similar to the general capacitor, and it has a good C/V value, long life, and low leakage characteristics. In high reliability systems, the 315USC is usually used in lightning protection devices.
