Tight coupling (k ≥ 0.97) and 200 V isolation make the
ST526PND series of coupled inductors 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, as a common mode choke or as a
1 : 1 transformer.
