| Feb 24, 2020 at 19:08 | comment | added | MathieuL | @johnny_boy Yes, I am pretty sure this is the ESR. ESR mean equivalent serial resistance. This include all the loss from all the effects present in the capacitor. ESR make it easier to have a lump resistance that represent the loss at different frequency. | |
| Feb 24, 2020 at 19:04 | comment | added | MathieuL | @DKNguyen Those are dielectric loss. The permittivity can be a complex number. The loss will increase with frequency to reach a maximun and than diminish as the frequency increase passing a certain point. | |

| Feb 24, 2020 at 19:02 | comment | added | John M | I don't think it's ESR cause the order of magnitude doesn't line up (I've never heard of a ceramic with 10 - 100 ohms ESR). I also have no idea why ESR would vary so much in a ceramic over freq. Then again, I'm not a chemist lol. Could just be a badly edited datasheet. | |
| Feb 24, 2020 at 18:58 | comment | added | DKNguyen | Huh. Good question. I never noticed that ESR varied with frequency. I always just kidn of tuned it out when looking at the impedance curve. I guess that means there is a real power loss that is frequency dependent? | |
