Probably that was the reason they did it that way. Božo that sounds like a nice and plausible explanation. Probably that was the reason they did it that way.

Tbh, im suprised to see magnetics seperate on a laptop where space is critical Most mobos these days have the magnetics integrated in to the connector to reduce the amount of board space required.

This chip was taken from a laptop motherboard, but i also desoldered parts from two desktop computer motherboards and i haven't found anything like this on them. thanks guys for clearing things out.

My guess is that they just stuffed some inductors into a plastic case to make it easier for the machines assembling the circuit board to place/solder. That’s weird…

They're used between RJ45 plug and the ethernet MAC controller. This stuff is ~ common, but this ref isn't. Bye This looks like a ethernet transformer.
