Bobbin Cores

Bobbin Cores Common Applications of ferrite bobbins include power applications, filtering, EMI suppression, and high Q inductors. MMG offers ferrite bobbins in a variety of materials and sizes. The ferrite bobbin design is a popular geometry due to its high current handling capabilities, the stability of inductance, and ease of winding as well as the electrical stability. Ferrite bobbins can be easily wound with high numbers of turns yielding high inductance, high stability, inductors.

MMG North America manufactures bobbins both leaded and unleaded in several configurations, surface mountable, axial leaded, and radial leaded. Parts can be packed on tape and reel for auto-insertion.

Below is a list of popular core sizes.
