Nanocrystalline Cable Cores

Würth Elektronik WE-NCC Nanocrystalline Cable Cores provide broadband suppression of conducted electromagnetic interference (EMI) in cable assemblies. These cable cores offer high temperature stability and ultra-high permeability in a single design. Compared with conventional manganese-zinc (MnZn) and nickel-zinc (NiZn) ferrite cores, the WE-NCC nanocrystalline cores offer up to 90% higher impedance across the 100kHz to 100MHz range. The housing has a UL 94V-0 flammability rating for a robust, application-ready solution. These features ensure that Würth Elektronik WE-NCC Nanocrystalline Cable Cores deliver stable magnetic behavior over a broad temperature range and effective filtering across a wide frequency spectrum.
