1) Typical Inductance with no DC. Tolerance
of +30% / -20% Request detailed data sheets
for specific test conditions.
2) Current which will produce the specified
percentage reduction in Inductance.
3) Maximum DC current. This value is for a
40
O
C temperature rise due to copper loss.
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.
