The MS612PND series of coupled inductors was designed
for high temperature applications â up to 155°C. Tin-lead
(Sn-Pb) terminations are used for the best possible board
adhesion.
The excellent coupling coefficient (k ⥠0.98) makes it ideal
for use in SEPIC applications. In SEPIC topologies, the
required inductance for each winding in a coupled induc-
tor is half the value needed for two separate inductors,
allowing selection of a part with lower DCR and higher
current handling.
These inductors provide high inductance, high efficiency,
excellent current handling and 500 V isolation in a very
rugged part. They are well suited for use as VRM induc-
tors in high-current DC-DC and VRM/VRD controllers.
They can also be used as two single inductors connected
in series or parallel, as a common mode choke or as a
1 : 1 transformer.
