VITROPERM® Cores

Vacuumschmelze (VAC) VITROPERM^® Cores are manufactured with tape wound nanocrystalline material that features higher permeability when compared with the ferrite cores. These cores offer permeability that ranges from 25,000 to over 100,000 compared to the 5000 to 15,000 range of the ferrites. The high permeability of the nanocrystalline core material achieves superior characteristics at low, middle, and high-frequency ranges when an optimizing winding arrangement is selected. Vacuumschmelze VITROPERM cores are enclosed in a plastic casing that is suitable for direct winding and offers good mechanical protection of the nanocrystalline core material. This casing allows the best magnetic properties and highest permeability levels to be maintained. VITROPERM cores are available with different A_L-levels for many core sizes. The common-mode chokes with toroidal tape wound cores of VITROPERM allow the effective attenuation of asymmetrical and conducted high-frequency noise.
