This is just a gripe. Throughout the electronics world polarized components are marked with the stripe or other distinctive marking on the positive terminal. That's fine. But why is that on SMD LEDs the dot and/or green stripe is on the negative side
(the cathode)? For through-hole versions, LEDs follow the usual convention, with the positive terminal having the long lead. But only in the SMD versions is it reversed. I know this, of course, so I adjust accordingly, but every time I need to remind myself of this I wonder how such standard-setting error could have happened. Does anyone know?
