UWE-12/10-Q48N-C is a wide input, isolated “Eighth Brick” DC-DC converter from Murata. Sometimes, you may see the “REV.E” listed on the label, as shown in the figure below. Is there any difference between REV.D and REV.E?
There is no functional difference between these two revisions. The revision is because some of the components in REV. D went obsolete and required replacement with new alternatives. REV.E and REV.D products both still conform to the manufacturer specification.
