High-saturation cores suit asymmetric filtering

A Magnetec product story

Edited by the Electronicstalk editorial team Nov 6, 2006

Nanocrystalline core material offers three times the saturation flux density at the same level of permeability of other ferrite materials.

To date, nanocrystalline cores have not be used in applications with significant DC preload because they saturate early thanks to their high permeability level.

Magnetec now offers high-saturation cores that enter into a low permeability range of typically 2000-8000.

Those cores are ideal for use in EMC filters for applications with a high level of asymmetric interference current (such as inverter drives).

Nanoperm LM nanocrystalline core material offers three times the saturation flux density at the same level of permeability of other ferrite materials.

Another field of application is in precision current transformers for household energy meters which are currently equipped with very expensive cobalt-amorphous cores.

Here, the new material offers a significant cost advantage.

The new Nanoperm LM series cores will be offered to public for the first time at Electronica 2006.
