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...
With contact terminals on the shorter sides, multi-layer ceramic capacitors (MLCC) usually come in a non-square rectangular package. Thus, the device between the contacts is longer than wide ("long" MLCC). Say, a 0805 package is 2.0mm long and 1.25mm wide, having contacts on the 1.25mm wide...
