It's generally two inductors wound on a single core for common-mode choking.
The result is that total common-mode inductance is 2*L while
differential-mode inductance cancels and equals zero. The 2200pF caps are
differential-mode shunts to ground. Some of these modules can be purchased
with complex combinations of both common-mode and differential-mode
inductance and capacitance sections. I use them for almost all home-brewed
projects that require an AC supply.
