It is why I love talking about them so much! Hioki USA loaned me an LCR Meter that works as an Impedance Analyzer to try out some measurements. As a result, I noted a few things that might catch someone off guard if they have never attempted to characterize capacitors. For example, many of us know about the MLCC DC Voltage Coefficient. However, do you know how to evaluate whether your parts lose 20 or 80% of their capacitance? Or, what considerations do you need to make when measuring a polymer electrolytic versus a film capacitor?

Unlike a DMM, these meters apply an AC signal (from 100 Hz to 100 kHz) to determine the reactive component of an inductor, capacitor, or resistor. A simple example here is a low-pass filter. See how the ideal and measured cut-off frequency varies. And THEN, see how it compares between a PCB and a Breadboard.
