Ferrite toroid transformers provide an often convenient and very effective shape for many wide band, pulse and power transformers and inductors. The continuous magnetic path yields the highest effective permeability and lowest flux leakage of any shape. Basic considerations: The inductance may be calculated from (the units are in CGS system which is used throughout this catalog). Here le and Ae are the effective magnetic path length and cross sectional area of the core, . is the effective permeability of the material, and N is the number of turns. This formula may be used for any shape under all conditions provided...
