Power Line Filter Modules are important components of circuit applications. They are used to provide EMI/RFI noise suppression. The FN2412-25-33 is a power line filter module that is typically used in industrial electronics, computer, control equipment and communication equipment. It is designed to provide common mode and differential mode attenuation up to 50 dB. It also provides good surge protection and broad frequency coverage.

The FN2412-25-33 consists of a combination of passive components such as capacitors, inductors and resistors. It has a low insertion loss of 0.1 dB while providing up to 50 dB of attenuation for common mode and differential mode interference. The device is designed for use on 50 Hz and 60 Hz AC mains networks. The module also provides good transient protection from over-voltage transients. The FN2412-25-33 is packaged in a surface mount package with a footprint of 12.5x15.0 mm.

The FN2412-25-33 has a metal case construction and is lead-free and RoHS compliant. It has a compliance voltage of Class II 250VAC and a working temperature range of -40°C to 105°C. The module is designed with an optimised damping circuit to suppress EMI/RFI noise which is generated by the connected equipment. It provides protection against the harmful effects of line-ground transients.

The FN2412-25-33 power line filter module has the following working principle: the inductors and capacitors are inserted in series in a circuit so that the magnetic field generated by the inductor is effectively shielded by the capacitance created by the capacitor. This creates a low-pass filter which allows only frequencies below the ‘cut-off frequency’ to pass through. The cut-off frequency is determined by the nominal value of the inductors and capacitors.

The FN2412-25-33 is capable of attenuating high-frequency noise up to 50 dB and providing even higher attenuation at lower frequencies in both common mode and differential mode configurations. The module also provides a high degree of immunity to over-voltage transients, making it ideal for use in a variety of industrial electronics, computer, control equipment and communication equipment. It has become a popular choice for those requiring an unobtrusive power line filter that provides reliable performance.
