This ferrite provides an optimal EMC solution for FPC and FFC applications. Sintered ferrite in sheet form exhibits superior insulation properties compared to materials incorporating metallized parts. It offers
high insertion loss and excellent EMC suppression in the low-frequency range (30 MHz to 300 MHz) compared to metallized EMC suppression sheets.
