Where I_MAX is greater than IDC @90%, the
Inductors can be used for Swing Requirements
producing a minimum Swing of 10:1.

Where I_MAX is greater than IDC @95%, the
Inductors can be used for Swing Requirements
producing a minimum Swing of 20:1.
Dimensions are nominal, based upon largest
wire size used with each toroid size. Smaller
wire will result in slightly lower dimensions.
