# Capacitor PPM equivalent?

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.

• My SPICE sim does tolerance and temperature effects separately, how would I go about making a simulation over temperature accurate? Aug 11 '20 at 22:27
• How stable do you need it? Aug 11 '20 at 22:37
• What do you mean by stable? Aug 11 '20 at 22:47
• initial error and temperature error Aug 11 '20 at 23:10
• 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. Aug 12 '20 at 1:06
