Nanocrystalline cores are cost competitive

Chokes with nanocrystalline cores have been recognised for many years as an ideal technology for use in EMI filters for any kind of switched power supply.

Chokes with nanocrystalline cores have been recognised for many years as an ideal technology for use in EMI filters for any kind of switched power supply.

This is has been particularly true where small size and high attenuation are both required at the same time.

But in many projects compromises have to be made due to cost restrictions, and so standard solutions such as ferrites are used.

A new range of Nanoperm LC cores from Magnetec offers an alternative also for cost sensitive applications.

The cores are designed with a relatively small "wall thickness", and the outer dimensions are similar to those of established ferrite solutions.

The concept works because of the very high effective permeability of the nanocrystalline core material.

The technical advantages are a very high operational temperature of up to 180C, the extreme robustness of the cores and the typical wideband attenuation characteristic up to the megahertz-range.

The new Nanoperm LC series cores will offered to the public alongside Magnetec's other new developments during Electronica 2006.
