Manual entry of bobbin window width in expert
Is there a way to manually enter the bobin window width in Expert? It can be done in xls very easily. Unfortuatnely, the first design I did in Expert 8.0 requires an EE25 and the bobbin width is incorrect. The common EE25 vertical 5+5 extended creepage bobbin that I use for PI designs is from Yih Hwa and measures 10.8mm.

I would agree that there is variance between Manufacturer's but transformer bobbins do not have large tolerances. They are actually quite tight. I would recommend that you at least update the bobbin width data in expert for the EE25. The common Yih Hwa EE25 bobbin that PI uses has a window of 10.5-10.8mm which is way off from 9.8mm. The bobbin width data in Xls is almost correct. I'm not sure why the data would differ from expert to xls. I figured out how to load in new bobbins into the transfomer library.
The bobbin width has quite a large tolerance and whats more is that it varies from manufacturer to manufacturer... You can add a new core and bobbin combination and use this in your design if you want the softwarw to use the exact number your manufacturer specifies...
