The thickness of the board beneath it gives deceptive scale. It’s about 50mm tall and the toroid is 85mm in diameter.

I was looking for much smaller CMCs. Also the datasheet for this part doesn’t have impedance-versus-frequency graphs so I refuse to buy it anyway :P
Choke? I know a fluxcapacitor when I see one!
