Ferrite beads avoid high-frequency interference on electrical cables. If filtering the interference on the correction cable fails to create sufficient protection, ferrite beads must be inserted within the device itself or directly at the plug connectors. For DC wires with low-frequency ripples, such as serial interfaces within EDP, ferrite beads are the answer. In contrast to broadband suppressor filters, ferrite beads provide damping only for individual wires. In circuits that are particularly critical, only the wire legs of electronic components are provided with ferrite beads, thus damping the interference at its very source. Bürklin offers a comprehensive range of ferrite beads, either as SMD components insertion machines or as pure cores.
