Learning More about Toroids and Ferrite Cores

A ferrite core can be described as a homogeneous ceramic structure (dense) that is created by mixing oxides of carbonates of metals (zinc, nickel, magnesium, manganese) with iron oxide. The final product is created by pressing the toroid in a fired kilim (roughly 1300o C). After cooled, the toroid is machined to allow it to meet specific operational requirements.

A Ferrite core has many advantages over other magnetic materials. This is mainly due to their low eddy current loss across a large frequency range. They are also highly electrically resistive. The above benefits, mixed with high permeability, makes this material ideal for use in high-frequency circuity (ranging from 10 kHz to 50 MHz). Common applications include:

  • High-frequency transformers
  • Wide-band transformers
  • Adjustable inductors

Variations of ferrite exist so that users can get unique characteristics for specific applications.  Nickel-zinc ferrite function differently than manganese-zinc ferrite. Simply put, the nickel version has low permeability where manganese-zinc has high permeability. Besides the difference in materials, the geometries vary as well (allowing for flexibility and mechanical and magnetic parameters).

Our talented team of engineers can help you build custom toroids with ferrite cores. Do not design your toroid alone because we are here to help.
