Component identification, between USB-C switch IC and connector
$begingroup$
As the title really, can you identify this component?
It's on a line connecting a USB-C switch IC (PI3USB30532) to the USB-C connector and I believe the line is for Display port functionality.
How Critical are the values of this part as i have no way of finding them?

No worries. Are there any markings on them you can discern?

They look like dual resistor networks - perhaps termination resistors. You could try measuring them with a multi-meter, see if you get approx. 50Ohm or 100Ohm across them.

Most likely in-line ESD protection devices as they have pads for ground connection. They could also be common mode chokes.

This is an EMI choke. Take a closer look or check with a magnet - the body of this component is made of ferrite.

This component is called "Common-mode Choke". Example: Murata DLP11TB800UL2L.
The choke is placed into differential data line like this:
This CMC is meant to suppress common-mode ESD events and reduce unwanted emission (which may happen when the transmission line is not perfectly balanced).
See also TDK offerings and typical use of individual chokes.
These components don't incude TVS elements, these packages have more than 4 pins.
