The PFD3215 has a footprint less than 3.2 × 2.3 mm,
making this shielded coupled inductor ideal for applications
with limited board space. It is designed for use in a variety
of circuits including flyback, multi-output buck and SEPIC.
These inductors provide high efficiency and excellent cur-
rent handling in a rugged, low cost part.
They can also be used as two single inductors connected
in series or parallel, as a wideband transformers or as a
common mode choke.
