EMI Suppression Ferrite Beads

Würth Elektronik EMI Suppression Ferrite Bead product families include the WE-AFB, WE-AFB LFS, WE-SAFB, and WE-TOF series. The WE-AFB, WE-SAFB, and WE-TOF series all feature a ferrite core made of NiZn. This NiZn core allows for the best possible interference suppression and works in a broadband frequency range. The NiZn core ferrites are available in axial (WE-AFB) and toroidal (WE-SAFB) types. Würth WE-SAFB ferrite beads are smaller in size and used for cables with a diameter of 0.55mm up to 4mm. The WE-AFB LFS axial ferrite beads have an MnZn core. The MnZn core material is used for low-frequency applications from 150kHz and 30MHz.
