Questions with Ferrite Cores

  • Ask: What does a ferrite core do on a cable?

    Answer: Ferrite cores (chokes) provide an inexpensive, and effective, way of coupling high-frequency resistance into a cable in order to reduce the common-mode current, and hence the radiation (or pickup) from the cable.

  • Ask: What are ferrite cores used for?

    Answer: In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents).

  • Ask: Do ferrite cores make a difference?

    Answer: A ferrite core or bead can be added to an inductor to improve, in two ways, its ability to block unwanted high frequency noise. First, the ferrite concentrates the magnetic field, increasing inductance and therefore reactance, which impedes or 'filters out' the noise.


  • Ask: What are ferrite cores made of?

    Answer: 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.
