Cylinder and Round Block Cores

In case, when a required item is absent in the data book, Magnetics offers to arrange the assemble by using blocks on the base of powder materials produced by company.


Such approach is realized when producing XFlux cores with U-form (part number 00X081102062AU026) and I-form (00X081020062AI026) which are standard Magnetics units.

Designs with rounded block cores offer the advantages of having customizable structures, high current capability, and ease of winding when compared to conventional toroidal cores. Using Magnetics® Kool MMμ® material, rounded block cores and cylinders provide the benefit of consuming less powder and result in lighter weight and lower costs, a great economic option for your unique design. Rounded legs are well-suited for helical windings, making them desirable for high-current applications.

The figure 1 and table 1 show variants of assemble using such blocks on the base of Kool Mμ:

Potential options for high current and high power design can include::
  • Kool Mμ for loss-limited design
  • XFlux for high DC Bias performance
  • Assemblies with Kool Mμ and XFlux cores intermixed for balanced performance benefits
