I'm shopping for capacitors, and I expect good capacitor datasheets to have a graph of |Z| (the magnitude of the capacitor's impedance) as a function of frequency.
I was confused when I looked at page 2 of this datasheet for a Murata 10nF ceramic capacitor. There are 2 different graphs for the capacitor's impedance as a function of frequency. One graph says it is displaying |Z|, whereas the other graph says it's displaying "R". Obviously the 2 graphs are different, but what's the meaning of the second one? Is it ESR?
I googled around, but all I can find are descriptions of impedance.
