26x EMI Suppression Cores

Fair-Rite 26x EMI Suppression Cores are available in flat ribbon, round cable, toroidal, and ferrite bead suppression core variants. The ferrite beads are cost-effective and can suppress conducted EMI signals. The chip beads can be used in devices such as cellular phones, computers, laptops, and pagers. The Fair-Rite ferrite round cable and flat ribbon cores are intended for larger suppression parts.
