Coupled Inductors–MSD1260 ForFlyback,SEPIC
and other Applications
Tight coupling (k ≥ 0.94) and 500 V isolation make the
MSD1260 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 con-
nected in series or parallel, as a common mode choke
or as a 1 : 1 transformer.
