And you can use a common sense filter, 0.1uF as the filter cap for a 40A supply at 120 Hz? :) How about something like: 100 000uF? I thought about 100,000uF, > unfortunately in many parts of the world the ',' character means the > same as we use the '.' character! :) One fellow I worked with insisted on specifying all caps in picofarads to avoid this.. So that nice memory super cap is : 4700000000000pF -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
