Magnetics - Learn More about Ferrite Cores

Ferrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (Fe 2 O 3) 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 1300 o C, and machined as needed to meet various operational requirements.
