MAGNETICS - Ferrite and Powder Cores

They develop and manufacture soft magnetic components and materials. These are used in the Products in Power Electronics and RF Communications. A leading world supplier of precision, high permeability magnetic components and materials to the electronics industry.



MAGNETICS - Ferrite and Powder Cores



Product line include powder cores, ferrite cores, and strip wound cores for applications such as chokes, inductors, filters and transformers.



MAGNETICS - Ferrite and Powder Cores

Learn More about Ferrite Cores



Made from MnZn, ferrite cores offer economical solutions for high frequency power transformers and inductors, EMC filters, and other applications.



Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium.



Ferrite ETD Cores



ETD cores are an economical choice for transformers or inductors. ETDs offer a round centerpost for minimum winding resistance. Dimensions are optimized for power transformer efficiency. Typical applications of Magnetics ETD cores include differential mode inductors and power transformers.
