>In that sense, the 0R1 resistor would be a 100mR resistor, I think the 0R1 is the preferable notation here, as it really emphasises that it is LOW value. >and the 0F1 cap a 100mF cap. However these are at the HIGH value end of the spectrum, so to my way of thinking using 100mF would be better. This may be part of the reason why a 220k is written that way rather than 0M22. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
