Power Line Filter Modules are electrical components used to filter out impurities from power supply lines and audio and video signal lines, which can reduce the environmental noise interference of the device\'s normal operation. The FN660B-20-06 is a power line filter module with a variety of applications because of its special design and working principles.

FN660B-20-06 is made of molded plastic material, and its three-digit numeric suffix indicates the rated temperature, voltage and current of the product, respectively. The FN660B-20-06 has a rated voltage of 500V / AC and a rated current of 20A, and it is suitable for working in temperatures between -10 ° C to +85 ° C. It also has a built-in safety control capacitor of 0.25uF, which can be used to prevent overloads, thus protecting the power line and reducing the risk of short circuits.

FN660B-20-06 has wide application in the filtering of power supply lines. For example, it can be used in the power filtering of household appliances, industrial equipment, computers, and medical equipment. With its strong anti-interference capability, it can effectively filter out the system\'s electromagnetic interference, reduce the impact of high-frequency pulse current, and eliminate the mutual interference of digital circuits. It also can filter out high frequency disturbances caused by power frequency ripple.

The working principle of FN660B-20-06 power line filter module is quite simple. The module is a low-pass filter system. It has two terminals and there is a capacitor between them, as well as an inductor. The capacitor allows current to pass through at a certain low frequency while blocking the high frequency current. The inductor also has a similar function, allowing the low frequency current to pass through the system, while preventing the high frequency interference current from entering. In this way, the filter can block sparks and other power supply interference.

Overall, FN660B-20-06 power line filter module has a variety of applications due to its special design and working principles. Its strong filtering capability can effectively reduce noise interference and protect the power line from overloads. Therefore, it has been widely used in various domestic and industrial applications.
