The LPD5030 coupled miniature shielded inductors are

only 3 mm high and 5 mm square. They are 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.
