The KEMET Noise Suppression Sheet Flex Suppressor® is effectively designed for high frequency noise that is generated from the electronic devices. The flexible sheet is a polymer base, blended with micron-sized magnetic powders dispersed throughout the material. These sheets are effective for electromagnetic wave and resonance suppression, and can be cut into a variety of shapes and sizes.Electromagnetic wave suppression – the electromagnetic wave enters through the sheet and is suppressed by losing its magnetic structure Resonance suppression – controls the high frequency current and suppresses unwanted electromagnetic resonance by creating impedanceWide range of frequencies available from MHz band to GHz bandThin, flexible material used in portable equipmentVirtually no limitation to where it can be usedLess time required for installationEasily cut into any shapeHalogen-free
