Ok, I've had enough of fluffing around to get precision resistor values in the last few days, it's driving me nuts.
Does anyone know of a program that will select two suitable value resistors (series or parallel) when given a total value and a required percentage tolerance? i.e. if I want say 99K 0.1% made up of two resistors in series, I want it to tell me all the available options based on a suitable E12/24/48/96 etc range, lowest E range first would be best, and exact matches listed first of course.
I wrote a program many moons ago to do just this, but it only supported E12 and was a bit clunky. Of course the usual Googling brings up tons of resistor calculators of all sorts, but none that will do exactly what I want. Surely there is one somewhere...
Thanks. Dave.
