User Guide October 2016 – Rev 9 Notes on ESR ESR (Equivalent Series Resistance), as its acronym implies, is the value of resistance that is effectively in series with an ideal capacitor. No capacitor is ideal of course, the detailed equivalent circuit of a typical capacitor is very complex. -
Page 6: Analysing Capacitors
User Guide October 2016 – Rev 9 Analysing Capacitors is designed to analyse capacitor ESR in or out of circuit. The two test probes can be connected to the component any way around. Remember though that in'circuit testing can result in less accurate readings. : To minimise risk of damage to the unit, make sure that the has completed any previous analysis before attaching the test probes to the capacitor. - Page 7 User Guide October 2016 – Rev 9 Analysing Capacitors continued The ESR analysis typically takes under 2 seconds to complete, followed by up to around 10 seconds for the capacitance measurement (depending on the characteristics of the capacitor). As soon as a valid ESR reading has Measuring C...

Page 10: Typical Values Of Esr
User Guide October 2016 – Rev 9 Typical Values of ESR continued It is not possible to provide a definitive rule for values of ESR that are acceptable for all situations. & The expected value of ESR largely depends on the capacitance value and the voltage rating of the capacitor but also depends on temperature ratings and other factors. -
