18 ELECTROMAGNETIC NOISE SUPPRESSION SHEET Effective suppression of electronic equipment noise Noise is easily suppressed with the simple assembly. Attach, sandwich and wrap around.

Noise damping Noise level is lowered by loss effect of magnetic substance, with smaller reflection suffered by conductive shielding materials.

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 Suppression of antenna effects decreases the noise. Radiation noise is emitted by cables or patterns acting as an antenna. The magnetic substance reduce the noise by minimizing such antenna effects. Equivalent circuit without the suppression sheet L1 R1 Circuit board Equivalent circuit with the suppression sheet L1 R1 L2 R2 Suppression sheet Circuit board Electromagnetic Noise Suppression Sheets Magnetic foil film Sheet Heat + Electromagnetic noise suppression sheet Plate type cores MG MAB Flexible resin based product has a wide range of applications. CGE High thermal-conductivity type provides simultaneous heat solutions in applications where significant heat is generated such as IC, etc. Property comparison (reference) FFS Achieve a good balance between thinned ferrite and high-performance with the new manufacturing process. Attach MFM Effective for reducing electromagnetic noise at low frequencies and against leakage of magnetic flux. Problems for which the usual absorption sheet is not sufficient. Sandwich Wrap
