FLEX SUPPRESSOR®

KEMET FLEX SUPPRESSOR® is a composite sheet made by blending and dispersing micron-sized magnetic material powders in a polymer base. These sheets are effective for electromagnetic wave and resonance suppression or to improve the magnetic flux convergence, and can be cut into a variety of shapes and sizes. The KEMET FLEX SUPPRESSOR sheet effectively suppresses high-frequency noise generated by electronic devices. The noise currents in signal lines are attenuated by affixing the sheet on boards and cables. The radiation noise from cables that act as antennas is suppressed.
