What is NANOPERM: Material properties NANOPERM® vs Ferrite

NANOPERM®: high permeability, high saturation flux, low magnetostriction, …

Advantages result in: • Smaller designs • Higher energy density • Lower copper losses, …

Summary

Advantages of MR typeline:

advanced EMI suppression

stable at high temperature reduced losses

Better saturation behavior

The MR process

1. Having problem with EMI-Ferrite (Isat, Tmax, ae(f),..) 2. Replace 1:1 the R-Ferrite with NANOPERM® MR -> test 3. Next redesign, improved MAGNETEC solution (permeability, geometrie, Cx,Cy,...)
