 Kool
Mu® E-cores
Kool Mu powder cores are made of a ferrous alloy powder, which has low losses at elevated temperatures. Kool
Mu E-cores have a distributed air gap which makes them ideally suited for switching regulator inductors, flyback transformers, and power factor correction (PFC) inductors. The 10,500 gauss saturation level of Kool
Mu provides a higher energy storage capability than can be obtained with gapped ferrite E-cores, resulting in smaller core size. Kool
Mu E-cores are competitively priced against gapped ferrite E-cores and their distributed air gap eliminates gap loss problems associated with ferrites. Kool
Mu E-cores have significantly lower losses and substantially better thermal properties when compared to powdered iron E-cores.
For complete technical information regarding material characteristics, refer to the Powder Cores Design Manual and Catalog.
| Special Advantages of MAGNETICS® Kool Mu
E-cores |
- E-shaped geometry is manufactured exclusively by MAGNETICS
- the distributed air gap results in a soft inductance versus DC bias
curve
- available in four permeabilities, 26µ, 40µ, 60µ, and 90µ
- significantly better DC bias characteristics than gapped
ferrites
- higher energy storage capacity than ferrite, allowing the
use of a smaller core
- excellent performance over temperature
- lower core losses compared to powdered iron
