4206-020LF

EMI/RFI Filters (LC, RC Networks) are well known for their ability to reduce electromagnetic interference (EMI), sometimes referred to as radio frequency interference (RFI), on electronic equipment. The 4206-020LF EMI/RFI Filter is no exception and plays an important role in Electromagnetic Compatibility (EMC) by shielding against unwanted electromagnetic fields.

The 4206-020LF EMI/RFI Filter is a two-stage single-ended common-mode filter consisting of an inductor, a resistor and a capacitor all connected in series. The inductor provides high attenuation to the filter while the resistor and capacitor provide a impedance bridge to the filter’s input. This design ensures that any noise on the input line is moderated on its way to the output line.

The 4206-020LF EMI/RFI Filter is part of Murata’s 4206-series of EMI/RFI filters, and is designed for general-purpose use in a variety of applications. These applications may include in-circuit, board-level or device-level filtering of RF interference, thereby achieving safeguarding and conformance to EMC standards.

The 4206-020LF EMI/RFI Filter is suitable for a wide variety of applications including consumer products, medical equipment, automotive electronics, computer electronics and telecommunications. Its common- mode filtering capability and its low-pass filtering characteristics make it a great solution for reducing EMI/RFI at the source, or on the board level. It is also well suited for applications that require an advanced filtering solution that is both effective and cost-efficient.

The 4206-020LF EMI/RFI Filter works by attenuating any incoming noise signals before they reach the output line. It also prevents the output line from radiating noise and interference, thus keeping electromagnetic fields from propagating beyond the application’s intended boundaries. This helps to ensure that EMI/RFI from the application does not affect nearby systems, as well as safeguard the application from external EMI/RFI disturbances.

In conclusion, the 4206-020LF EMI/RFI Filter is a reliable and effective filter that provides an advanced solution for reducing electromagnetic interference. Its low-pass filtering and attenuation capabilities make it a great solution for applications that need a cost-effective solution to reduce EMI/RFI.
