Need step I can understand the anti-jamming core winding is what?

Anti-jamming core winding definition: electromagnetic waves and electronic components, produce interference phenomenon, called the anti-interference magnetic ring, for example, the common 'snow' on the TV screen said received signal interference. Anti-jamming core winding is an electronic device does not interfere with other equipment, also is not affected by other equipment at the same time, the circular electromagnetic compatibility as well as the security of the familiar, is one of the important indicators of the quality of the products, related to personal and property safety, and electromagnetic compatibility is related to personal and environmental protection. The anti-interference ability of anti-jamming core winding is characterized by the impedance characteristics. Present low sensibility in low frequency impedance value, does not affect the useful signal transmission on the data line or telecom, at high frequencies, about 10 MHZ, impedance increases, the inductance component remains small, resistive quantity increases rapidly, the high frequency EMI interference energy absorbed in the form of heat dissipation, usually with two key points 25 MHZ and 100 MHZ frequency calibration EMI interference resistance to circular and anti-jamming. As a round cable products, equipped with a size and shape two core coiling points directly without dismantling or cut off the original cable installation. Use video equipment, audio equipment, electric equipment, communication equipment, office automation ( OA) And other equipment, prevent and spontaneous noise absorption and intrusive noise. To prevent parasitic oscillation EMI series: good restrain electromagnetic interference characteristics, used for circuit connection or connect the wire and cable anti-interference. 1, prevent the plug wire when interference current shock; 2, preventing electromagnetic interference of the space, let the transmission stability. EMI absorption magnetic ring/magnetic beads from used to inhibit signal lines, peak power line noise and interference, it have ability to absorb electrostatic pulse at the same time, using electronic equipment electromagnetic compatibility ( EMI / EMC) And the corresponding international standard of electrostatic discharge. EMI absorption circular/magnetic beads absorption interference ability is characterized by the impedance characteristics, present low sensibility in low frequency impedance value, does not affect the useful signal transmission on the data line or telecom, at high frequencies, about 10 MHZ, impedance increases, the inductance component remains small, resistive quantity increases rapidly, the high frequency EMI interference energy in the form of heat absorption dissipation, circular and usually use two key points of frequency 25 MHZ and 100 MHZ calibration EMI resistance to absorb magnetic ring/absorption properties of magnetic beads.
