Hi All,
I wondered if anyone could help identify this little transformer from the SMPS in our coffee machine? I've replaced it with one from a slightly earlier model and regained full functionality of the machine, but I'd like to identify this and have a spare. No circuit diagram available or parts list I'm afraid. Its just a 4 pin device sitting right at the power input for the board and then feeds the bridge rectifier. The photo is of the removed part hence it only has two pins left....
Many Thanks

That is called a Common Mode Choke. It blocks interference from the SMPS so it doesn't contaminate the mains supply.
Many are available; https://uk.rs-online.com/web/p/common-mode-chokes/8996965 is a more up to date design but does the same thing.
