02622 Johnny Builds an ESR Meter. Episode III

The third and final episode of my ERS meter build. ERS stands for Equivalent Series Resistance and it is a property of all capacitors.

The big take away is a good test case will save you a good deal of time PCB Fab in a Box site https://www.pcbfx.com/ A special shout out to w2aew    / @w2aew   and his videos on the subject    • #5: My ESR Meter project from 2006      • #135: Measure Capacitor ESR with an O...   "I stand on the shoulders of giants."
