MSD7342 Series Applications

The excellent coupling coefficient (k ≥ 0.94) makes the

MSD7342 series of coupled inductors ideal for use in

SEPIC applications. In SEPIC topologies, the required

inductance for each winding in a coupled inductor is

half the value needed for two separate inductors, allow-

ing selection of a part with lower DCR and higher

current handling.

These inductors provide high inductance, high efficiency

and excellent current handling in a rugged, low cost part.

They can also be used as two single inductors con-

nected in series or parallel, as a common mode choke

or as a 1 : 1 transformer.
