I have a 10nF capacitor who's datasheet gives 10% tolerance, and 15% total tolerance over temperature (-55 to 125C). It does not give it in ppm, for simulation purposes, how would I calculate it's ppm value?

Thanks in advanced.

ppm means parts per million. 1 ppm is therefore equivalent to 0.0001%. 10% is equivalent to 100,000 ppm. Since this is such a large number, tolerances of this magnitude are not normally quoted in ppm but in percent.

  • \$\begingroup\$ Well I would like to be able to run Monte Carlo sims at set temperatures and have accurate results, so I guess my answer would be that I would like the two errors completely decoupled from each other. \$\endgroup\$
