Post by: cheerio on March 10, 2012, 16:56:37 PM

Hi, i am back :)

Does anyone know how to calculate the ESR values of capacitors?

welcome back cheerio!
by ESR you mean "equivalent series resistor" or the standard capacitor values (E6/E12)?

here are some graphs from an ESR meter kit I built some time ago - generally in repair one tends to compare similar capacitor ESRs
