The LPD4012 series of coupled miniature shielded inductors are only 1,1mm high and 4mm square. The coupling coefficient (k ≥ 0.94) makes it suitable 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 current handling in a rugged, low cost part. They can also be used as a coupled inductor, two single inductors connected in parallel, as a 1 : 1 transformer or as an autotransformer when connected in series.

The LPD4012 series of coupled miniature shielded inductors are available from Tri Components , the agent of Coilcraft.
