U configured Cores

Magnetics Inc. issues 12 standard sizes of U configuration that are made of Kool Mμ powder material and are intended for a use as magnetic circuits of chokes operating with high values of electric current. U-configured cores are made of Kool Mμ material which has a permeability of 26μ, 40μ , 60μ, 90μ and is characterized by low losses and by values of magnetostriction that approach to zero. In contrast to ferrite materials and to cores based on silicon steel, Kool Mμ cores do not lose their parameters at high temperatures exceeding 200°C.

Note:
1. To download from table a necessary pdf-file describing a required U-configured core click a value of AL corresponding with a material brand chosen by you.
2. "–" sign shows that a П-shaped Kool Mμ powder core is not issued with given permeability.

B-configured Plate

Magnetics Inc. issues 3 standard sized of B-configured plates made of Kool Mμ material and intended for a use as magnetic circuits of chokes operating with high values of electric current. B-configured plates are produced with a permeability of 26μ, 40μ and 60μ.
