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 ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...

Capacitors are essential components in electronics, primarily used for bypassing and decoupling. Depending on the capacitor type and its application, it is prone to aging and failure. Detecting a ...

Broadcast consultant Tom Osenkowsky recently constructed a panel with two vu meters and a DPDT switch. The switch allows him to configure the meters to display conventional Left and Right channels or ...
