EMI filter isalso known as RFI (Radio Frequency Interference) basically are passive electronic devices that are used to suppress conducted interference that is found on a signal or power line. EMI filters for power supplies, monitors, networking, instruments and medical equipment and many other tools used throughout the world.

Electromagnetic Interference is unacceptable electromagnetic emissions, which result in the degradation or malfunction of electrical or electronic equipment. RFI (Radio Frequency Interference) is detrimental electrical energy in the frequency range which is for the specific transmitted radio frequency. Major sources of EMI and RFI include, switching power supplies, microprocessors AC motors and electrical power cords. There are many different types of EMI filters at Future Electronics, we stock many of the most common types categorized by type like dimension/case size, impedance, DC resistance, maximumcapacitanceand rated current
