Unknown transformer : how to find a good replacement part ?

[the_rem]

Hello guys,

I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow me to fully understand it and find a good replacement part. May I ask anyone here to gently take a look at this datasheet and advise me for a good replacement part ?

Thanks,

Denis

For me to it too much work to go through a million transformers to find the right part but I'll help you on your way:
Wurth has a pretty nice selection of high frequency transformers.
But you will have to do the homework to find out what fits.
You can start with this on Mouser and then follow the links to Wurth's homepage: 750312279
