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 ...
A portable in-circuit ESR and DCR capacitor tester, the Model 881 uses a standard 9-VDC battery or optional AC wall adapter as its power source. The unit measures the equivalent series resistance of ...
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 ...
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 ...
There’s a problem with collecting old tube amps and vintage electronics – eventually the capacitors in these machines will die. It’s not an issue of a capacitor plague that causes new electronics to ...
The circuit in Figure 2 combines the sink currents of both the Output and the Discharge pins, which allows us to double the output current. Resistors R3 and R4 are part of the load, they limit the ...
[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 ...
