Toroid Cores

Toroid Cores Ferrite toroids are ring shaped components which can be used in a great variety of applications. Including EMI suppressors, chokes, transformers and inductors. Toroids have many design advantages, for instance, they have a uniform cross section which makes predicting electrical parameters a simple calculation. The closed magnetic structure of toroids confines magnetic flux within the core body which gives the structure good shielding characteristics as well as optimal inductance to core volume ratio.

MMG manufactures toroids in a wide range of materials and sizes from .08 inches to greater than 1 inch in diameter and can be manufactured in any of our materials in order to optimize the part for a given application.
