I have a circuit that failed on me and I think I have identified the faulty component. It is a common mode choke but has no identification marks on it. I have an identical board with the same component that works. How can I test it to get specs for a replacement? It is smd and picture is attached. Any help would be greatly appreciated. Its the square component at the bottom right. Thanks all.

Remove it and test with LCR meter to find value or if open. And welcome to AAC! It sure looks like a through-hole coil.
