Notice that in the TO92, one edge of all terminals fall on a line that bisects the case diameter were it to be totally round. The 'E' dimension is from the flat side to that line.]]> Wed, 19 Feb 2020 12:06:01 +0000 https://www.PCBLibraries.com/forum/e-dimension-in-to92_topic2604_post10620.html#10620 <![CDATA["E" dimension in TO-92 : In TO-92 family, is "E"...]]> https://www.PCBLibraries.com/forum/e-dimension-in-to92_topic2604_post10619.html#10619 Author: Batiskaff

In TO-92 family, is "E" dimension spacing from body edge to body corner

or from body edge to terminal edge?

Or may be from edge of body to terminal center, for example
