Coupled Inductors–MSD7342 Series
For SEPIC
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.
