1278 COUPLED INDUCTORS
Outgassing Compliant Coupled Inductors AE612PND
The AE612PND series of shielded coupled inductors
was designed with special materials that pass NASA low
outgassing specifications and allow use in high temperature
applications – up to 155°C.Tin-lead (Sn-Pb) terminations
are used for the best possible board adhesion.
They offer excellent coupling coefficient (k ≥ 0.98) and
can be used in SEPIC applications. In SEPIC topologies,
the required inductance for each winding 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.
