• Magnetic tape incorporating a soft magnetic alloy film has been developed to reduce the electromagnetic interference(EMI)noise current in an electrical cable.The advantage of the magnetic film compared to a ferrite core is shown using an eddy current loss model.The magnetic film exhibited the expected high-loss characteristics above 30MHz.Laminated resin gives the tape sufficient strength to be wound inside a cable sheath.The fabricated 60- and 90-μm-thick tape wound along the whole cable length exhibited noise reduction ratios of 4 to 5dB for both radiated emission in the range from 30 to 300MHz, and surge immunity with a magnetic substance whose volume was one-sixth that of a conventional ferrite core.The tape also exhibited no significant degradation in the mechanical and environmental tests and showed the practical durability.
