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 ...

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 ...

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 ...

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 ...

A single, simple measurement is described that allows the determination of the ESR required to achieve a desired phase margin, using a particular value of output capacitor. Solving the ESR requirement ...
