WE-TEFA Toroidal EMI Suppression Ferrites

Würth Elektronik WE-TEFA Toroidal EMI Suppression Ferrites feature a ferrite core made of MgZn, a material that works in a wider frequency range than NiZn. The MgZn core enhances the properties of EMI suppression in the middle frequency range, ensuring it will attenuate the EMC interferences earlier. Würth Elektronik WE-TEFA Ferrites are ideal for data and signal lines, coaxial cables, multiconductor wires, and multimedia cable interfaces.
