Applications

At only 1.4 mm high and 3 mm square, the LPD3015

is Coilcraft’s smallest shielded coupled inductor. It is

ideal for use in a variety of circuits including flyback,

multi-output buck and SEPIC.

These inductors provide high inductance, high efficiency

and excellent current handling in a rugged, low cost part.

They can also be used as two single inductors connected

in series or parallel or as a common mode choke.
