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 ...
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, ...
The bench-top model 889A LCR/ESR meter makes in-circuit measurement of common component parameters�such as conductance, Q, parallel and serial inductance and capacitance, and equivalent series ...
Capacitors are classified according to their dielectric’s type. Electrolytic capacitors are popular in power electronic circuits, due to their high volumetric efficiency and excellent price ...
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 ...
