The magnetic composite is composed of Fe-Si-B-Cr amorphous particles with a mean diameter of 6 mu m and epoxy resin. From the experiments using the PCB-TEG with a 130 mum/50 mum line/space and 25-mm line length, the crosstalk was suppressed in the wide frequency range by using the magnetic composite. In the case of using 51 vol.% amorphous composite, the crosstalk suppression was up to 20 dB around 1 GHz.
