Common-mode choke
A magnetic component with two or more windings on a shared core, wound so that differential load current cancels the flux while common-mode current sees a high impedance.
It attenuates common-mode noise without saturating on load current.

Notes
Its leakage inductance is deliberately exploited to provide differential-mode attenuation at the same time.
