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, ...

Our recent discussion about checking capacitors for equivalent series resistance continues with tips from two engineers with plenty of field experience. The first is from engineer Ed Treese. Ed writes ...

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 ...
