As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

[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 low ...

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 ...

Smart Tweezers ST5S-BT is based on the popular ST-5S model of Smart Tweezers; this model offers the most features and functions as well as a basic accuracy of 0.2%. The Bluetooth enabled model can ...

Got a bunch of questionable electrolytic caps sitting in your junk bin? Looking to recap a vintage radio chassis? Then you might need to measure the equivalent series resistance of the capacitors, in ...

Ideally, I'd like to get one of these models, assembled and working, but I may accept a kit with all the parts present (like the one using the Blue LED):<BR><BR>ESR Micro v3.1<BR>ESR Micro ...
