MAGNETICS Ferrite toroids Ferrite Toroid Cores

Ferrite toroids offer high magnetic efficiency as there is no air gap and the cross-sectional area is uniform.  MAGNETICS® toroids are available in many sizes (O.D.'s from 2 mm to 140 mm) and materials (permeabilities from 2,300 to 10,000).  If you require a size that is not listed, e-mail a MAGNETICS Application Engineer.

MAGNETICS can meet several special requirements in the manufacture of these cores.  Different coatings can be applied to increase winding ease and improve voltage breakdown.  Cores can be color-coded to distinguish different materials, and by adding coating thickness, we can provide a higher than standard voltage breakdown guarantee (contact the factory for a custom specification).

Special Advantages of MAGNETICS Toroid Cores
  • wide range of sizes
  • 6, 8, 10 and 14 pin headers
  • easy mounting
  • exceptional manufacturing capabilities
  • consistency and uniformity
  • compact packaging on PCB
  • easy, low-cost assembly
