Power Line Filter Modules (PFLs) are electronic devices used to reduce or filter the disturbances generated by electrical surroundings. In general, PFLs serve to reduce the noise that is generated from interfering signals or components and to ensure the proper operation of the electrical system. The FN5020-25-33 is one type of PFL, specifically an AC UL approval power line filter module, used to comply with US UL1411 industrial standards.

The FN5020-25-33 is designed for use in industrial processes and equipment, data processing, and other applications requiring low leakage current and electromagnetic shielding. It provides strong filtering performance while maintaining a low profile, with a working temperature range of -25°C to +80°C and an operating current range of 0.22A to 12A. This PFL also offers a minimum insertion loss of 30dB for rejection of 60Hz noise.

The FN5020-25-33 includes four common-mode capacitors, two Y-type capacitors, one common-mode choke, and a double-layer electromagnetic-shielding structure. The four common-mode capacitors, two Y-type capacitors, and common-mode choke provide severalfilters for both differential-mode(DM) and common-mode(CM) noise, which is sent from surrounding power lines. Additionally, the double-layer electromagnetic shields help reduce the capacitive coupling in the power system, while also providing extra protection to sensitive components.

The FN5020-25-33 meets diversified requirements by providing a reduction in conducted interference on the power lines and decrease radiated noise. The module also reduces the impact of external electric fields on sensitive components, while also providing a reliable connection for the power system. The combination of the components form a low-pass filter that acts to reduce the power line noise.

The FN5020-25-33 is reliable and easy to use, providing a simple way to reduce conducted noise on power lines. It is designed with a compact size for easy installation and integration into machinery and systems. As a UL-approved module, it is acceptable under certifying standards, ensuring safe and efficient operation of the power system.
