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 ...

Optimized for high-speed testing and low ESR measurements on tantalum and other types of capacitors, the 1930 capacitance meter features a fast settle time and quick recovery from open or shorted ...

Capacitor (n): a troublesome electronic component that accumulates and discharges trouble for other components. I can’t prove it, but I’ll wager that capacitors are near the tops of everyone’s ...
