The excellent coupling coefficient (k
MSD1260 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, allowing
selection of a part with lower DCR and higher current
handling.
These parts provide high inductance, high efficiency
and excellent current handling in a rugged, low cost
part. They are also well suited for use as a VRM
inductors in high-current DC-DC converters and VRM/
VRD controllers.
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.
Core material Ferrite
Terminations RoHS compliant matte tin over nickel over phos
bronze. Other terminations available at additional cost.
