EMI/RFI Filters: Shielding Devices from Interference in a Connected World
EMI/RFI filters are essential components that protect electronic systems from harmful electromagnetic and radio-frequency interference. These filters ensure that devices operate efficiently, maintain signal clarity, and comply with regulatory standards, making them crucial in sectors such as telecommunications, healthcare, and manufacturing. What Are EMI/RFI Filters? EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) filters are passive components that block or reduce unwanted electromagnetic or radio-frequency signals. EMI refers to disturbances in an electronic device caused by electromagnetic fields, often generated by power lines, motors, or other electronic equipment. RFI refers to high-frequency interference caused by radio waves, which can come from communication towers, wireless devices, or other sources emitting radio signals. How EMI/RFI Filters Work EMI/RFI filters typically incorporate components like capacitors, inductors, and resistors to creat...
