Coupled Chip Inductors  PFD2015 ForFlyback,SEPIC,Zeta
and other applications
With a footprint of 2.2 × 1.45 mm, the PFD2015 is Coil-
craft’s smallest shielded coupled inductor. It is ideal for
use in a variety of circuits including flyback, multi-output
buck, SEPIC and Zeta.
These inductors provide high efficiency and excellent
current handling for parts this small.
They can also be used as two single inductors connected
in series or parallel, as common mode chokes or as
wideband transformers.
