CoupledChipInductors–PFD3215

For Flyback,

SEPIC and other

applications

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.
