What is the difference between nickel-zinc and manganese-zinc ferrites? MnZn materials have a high permeability, while NiZn ferrites have a low permeability. Manganese-zinc ferrites are used in applications where the operating frequency is less than 5 MHz. Nickel-zinc...

What is a ferrite core? Ferrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (Fe2O3) with oxides or carbonates of one or more metals such as manganese, zinc, nickel, or magnesium. They are pressed, then fired in a kiln to 1300o C, and...

How important is permeability in power materials? Permeability is flux density, (B), divided by drive level, (H). Power materials are generally used for high frequency transformer applications. Hence, the important characteristics are high flux density and/or low core...

Customized ferrite cores … a few things to consider before introducing a new design Custom cores do not necessarily follow published data values. Many parameters must be considered, for example, mechanical tolerances. A figure of +/-2% is a guide due to shrinkage from...

Magnetics® soft ferrite cores are an oxide made from Iron (Fe), Manganese (Mn), and Zinc (Zn) which are commonly referred to as manganese zinc ferrites. They have a low coercivity and are also known as soft magnetic ferrites. Because of their comparatively low losses...
