EMI/RFI Filters (LC, RC Networks) are specialized components designed to attenuate unwanted electromagnetic interference (EMI) and radio frequency interference (RFI) in electronic circuits. These filters use a combination of inductors (L) and capacitors (C) or resistors (R) to create low-pass or band-pass filter networks.
Highly effective in cleaning up power lines and signal paths, they are employed in a myriad of applications including industrial machinery, medical devices, and consumer electronics. Key manufacturers include AVX Corporation, Panasonic, and Murata Electronics.
EMI/RFI Filters are crucial for meeting regulatory standards and ensuring the reliable operation of sensitive electronic equipment.
