Detecting a failed capacitor is easy sometimes just by performing a visual inspection, but there are many cases in which you would need an LCR meter to spot any failure. In this article, I covered the most common failure cases of electrolytic, polyester (MKT), and ceramic (MLCC) type capacitors...
In this video, I talked about 3 types of failure in the electrolytic capacitors and how to detect them. You might need a benchtop multimeter or an LCR meter to detect all failure types.
Hi.
I've bought my first LCR meter, capable of testing at 100 Hz to 100 kHz.
It can measure ESR in Cs mode (capacitance, series measurement).
For electrolytics, it seems to work fine.
But, if test a good 100 nF ceramic capacitor, it measures hundreds of ohms resistance, which it obviously must...
