E6D05:

What is one reason for using ferrite cores rather than powdered iron in an inductor?

  1. Ferrite toroids generally have lower initial permeability
  2. Ferrite toroids generally have better temperature stability
  3. Ferrite toroids generally require fewer turns to produce a given inductance value
  4. Ferrite toroids are easier to use with surface mount technology
