Tight coupling (k ≥ 0.97) makes the ST512PJD series
of coupled inductors ideal for use in a variety of circuits
including flyback, multi-output buck and SEPIC.
These coupled miniature shielded inductors are 3.5 mm
high and 6.0 mm square. They provide high inductance,
high efficiency and excellent current handling in low
cost part.
They can be used as two single inductors connected
in series or parallel, as a common mode choke or as a
1 : 1 transformer.
