It must be on a very old schematic ----- Original Message ----- From: "Matthew Brush" To: Sent: Wednesday, June 02, 2004 6:38 AM Subject: [EE:] Silly Question, what is CR Hello all. I have a super easy question. I've been looking at a lot of scrap circuit boards kickin around here, and I always notice little parts (usually look like SMT transistors) which are silkscreen labelled CR1, CR2, etc... What does CR stand for? The only thing I can thing of is Comparator. Is that right? Thanks ahead of time. MJ Brush -- http://www.piclist.com hint: The PICList is archived three different ways.
