Ferrite Cores

Ferrite cores are a magnetic device used in the windings of transformers or other wound components. The chemical makeup of these devices help to prevent eddy currents. These are created in different form factors such as: E, toroid, ER, multi-hole, etc. and come in many different sizes. Key parameters are going to be the size, form factor or core type, and inductance factor.
