VACUUMSCHMELZE GmbH & Co. KG (VAC) is one of the world's leading manufacturers of metallic
materials and magnetic components made from these alloys. The unique combination of high
permeability with very low losses of VAC's nanocrystalline (VITROPERM©), amorphous (VITROVAC©) and
crystalline NiFe (ULTRAPERM©) alloys is the basis of the innovative VAC core range.

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 chosen. 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. 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
holder of over 600 patents. The company is among the world's most highly innovative developers of
advanced industrial materials.
VAC's range of products comprises a broad array of advanced semi-finished products, components,
parts, modules and systems for use in a wide variety of fields and industries spanning watch-making and
medical technology, regenerative energies, shipbuilding and telecommunications, and the automotive
and aviation industries. VAC's custom solutions are developed in close collaboration with the customer,
reflecting the company's expertise in materials and state-of-the-art production technology.
