You nailed it, I checked that link and that is the exact part. Another thanks!That looks like remnants of a small common mode choke. E.g. https://product.tdk.com/system/file.../catalog/cmf_commercial_signal_acm2012_en.pdf
Cleaning the board should reveal more. If there are 4 pads then it is a common mode choke.
