Flat Ferrites & Ferrite Cores

Würth Elektronik Flat Ferrites and Ferrite Cores include three series: WE-FLAT, WE-SPLITRING, and WE-SFA. The WE-FLAT ribbon cable suppressors provide an easy solution to filter interference on flexible printed circuit boards, ribbon cables, and more. The WE-FLAT series utilizes a NiZn core material for wideband noise suppression from 1MHz to 1GHz. The WE-SPLITRING split ferrite cores are easy to mount on already installed cables and are suitable for computers, terminals, and data lines. The WE-SFA series features flat clip-on modules with a 4 W 620 ferrite material, and they are ideal for computers, terminals, data lines, and more. Würth Elektronik Flat Ferrites and Ferrite Cores operate in a temperature range of -25°C to +105°C or +125°C, depending on the series.
