2 18 ELECTROMAGNETIC NOISE SUPPRESSION SHEET Effective suppression of electronic equipment noise Noise is easily suppressed with the simple assembly. Attach, sandwich and wrap around. Broad range of variations, sheet, core, heat-conductive types etc. Custom cutting and secondary processing are available. Noise damping Noise level is lowered by loss effect of magnetic substance, with smaller reflection suffered by conductive shielding materials. reflection large Shielding material damping small reflection small Suppression sheet damping large Radiation noise is emitted by cables or patterns acting as an antenna. The magnetic substance reduce the noise by minimizing such antenna effects.
