You want me to push for it, and you'll tag along when you think >it's safe? Nope - that's not how I see it. Two things to think about: the old-timers are getting out of the business (and dying off, unfortunately) - and - large size capacitors occupying small volumes are slowly becoming more common. I'm saying that I think that it will take another decade for both of those things to happen. At that time, using terms like "mF" will be commonly accepted. In the meantime, I think that writing "1000 uF" is entirely reasonable and correct. When might I use the term "mF"? Probably if I'm dealing with really large capacitors. Instead of writing just 10,000 uF or 25,000 uF - I'd probably write it both ways as "25,000uF (25mF)". dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
