• Isat is the sum of the current flowing in both windings. DCR is the maximum per winding.
• When windings are connected in parallel, inductance is the same value and DCR is half the value shown.
• When windings are connected in series, inductance is four times the value and DCR is twice the value.

1 Find your required inductance in the far left column.
2 Scan the row until you find the desired current rating (bold number); parts from there to the right meet your requirement.
3 Read up to see the Coilcraft product series and dimensions.

Typical Applications
Coupled inductors are ideal for use in a variety of circuits including flyback, multi-output buck and SEPIC. They can also be
used as common-mode chokes.
These parts offer excellent coupling coefficient (k ≥ 0.98); and provide a wide range of inductance values, high efficiency and
excellent current handling.
In SEPIC topologies, the required inductance for each winding is half the value needed for two separate inductors, allowing
selection of a part with lower DCR and higher current handling.
