At only 1.4 mm high and 3 mm square, the LPD3015
is Coilcraft’s smallest shielded coupled inductor. The
excellent coupling coefficient (k
≥ 0.97) 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 efficiency and excellent
current handling in a rugged, low cost part.
They can also be used as two single inductors con-
nected in series or parallel, as a common mode choke
or as a 1 : 1 transformer.
