A simple and direct method for measuring ESR is proposed in [3], in which the ESR is determined directly by the ratio of the capacitor’s ripple voltage to ripple current.

This ESR actually has multiple constituent elements, including the part contributed by the electrodes and terminal leads, as well as that due to the dielectric, plate material, electrolytic solution, ...

With [Paulo]’s DIY ESR meter, of course. An ideal capacitor has a zero equivalent series resistance, and failure of a capacitor can be seen as an increase in its ESR.

[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor under test had a lo… ...

A simple modification double’s the output current of a 555 circuit and finds utility in applications that measure ESR.

Longtime contributor Bob Meister from Hamden, Conn., writes in response to Tom Osenkowsky’s recent contribution with respect to equivalent series resistance (ESR) and the Sencore LC-75 Z-Meter being ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester. It measures ESR and DSR from 0 ...

The Capacitor Wizard measures ESR with the capacitor “in-circuit.” Its ESR meter’s low input impedance, simplicity of use and real-time measurements still make it the fastest and most reliable ESR ...
