Toroid is the optimal shape for magnetic induction due to its perfectly closed magnetic circuit and homogenous cross section, thus achieving the highest inductance per turn (AL factor). This shape is specially suitable for common mode chokes, transformers, baluns and other applications where high inductance is required.

Ferroxcube provides a complete range of sizes from 2.5 mm to 152.
Ferroxcube toroids exhibit smooth and soft chamfered edges optimal for winding without damaging the wire isolation. Coatings provide breakdown voltage protection; epoxy, nylon or parylene ® are chosen depending on core size and ferrite material.

Energy storage performance can be optimized by gapping the core: checkout the range available.
