Thanks for your help. It seems I wised up and did a search for '10G ethernet common mode filter' and for anyone who reads this benefit there is a specific type required: Common mode filter for ultra high-speed differential signal line​ type ALC2012H from TDK/Mouser. Good thing I will not be ordering a standard signal line common mode filter.

I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.

The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.

Sorry, I am not experienced hence a basic question.
