VAC nanocrystalline cores offer linear hysteresis loop and high permeability compared to other
magnetic cores. With over 30 years of experience manufacturing amorphous and nanocrystalline soft
magnetic cores, VAC offers state of the art technology, quality and performance.
Common Mode Chokes with toroidal tape wound cores of VITROPERM allow the effective attenuation
of asymmetrical and conducted high frequency noise. The high permeability of the nanocrystalline core
material achieves superior characteristics at low and middle frequencies, as well as in the high
frequency range, when an optimized winding arrangement is
In comparison to conventional ferrite, advantages over the entire frequency range are obtained.
VAC offers five new current sensor series for PCB mounting in which the electronics is integrated (for more on VAC sensors, visit our VAC Current Sensors page). Three
of the new series contain their own primary conductors; two series however are made with openings for
passing through separate primary conductors. The patented VAC principle of the compensation sensor
with magnetic probe as a zero field detector is
distinguished by maximum precision of the current detection.
Established in 1914, VACUUMSCHMELZE (VAC) designs, produces and markets advanced materials,
including magnetic materials, and related products. VAC today operates in over 40 countries and is the
