1260 COUPLED INDUCTORS
High Reliability Coupled Inductors ML590PND
The ML590PND series of shielded coupled inductors was
designed specifically for high temperature applications –
up to 155°C. 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 inductor 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.
