You can extract ESR and ESL values from the |Z| vs frequency chart. For the TDK one you can get similar info on TDK.com. | |

| Jan 31, 2019 at 6:05 | comment | added | D. Patrick | That's great information! I even feel like I understood nearly all of that. I don't understand the inductance as it relates to package size and why putting them in parallel might fix it. But that's something I can probably google. :) How do I compare ESR, ESL, or ripple current? I'm looking at the datasheet for the cap I picked and the only thing it mentions about those is that they are low. :) "Low self-heating and high ripple resistance due to low ESR." Thanks again! | |
