John Barnes presented some data he measured on several ceramic capacitor styles. How were they measured? Were they mounted on a test board, with traces and vias? Or bare components? Does the instrument fixturing contribute to the measurement? There seems to be a very wide range of both ESL and ESR within any group. Any idea why, especially for the ESL? Does it correlate with capacitance value, or vendor? You didn't happen to look at some "wide" capacitors (such as 0612), did you?
