3 ohms/volt dropper (5v = 15R dropper) to limit the surge was the standard I learnt and still use. Suitably adjusted/amended to allow for the load current. However I can not find the design notes that the value comes from, I have got them somewhere. The likely source is a Siemens databook from the 1980's. -- Regards Richard _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
