Depending on the capacitor type and its application, it is prone to aging and failure. 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 you will frequently encounter in your repair attempts. I considered four testing parameters: DC resistance, temperature, capacitance, ESR, dissipation factor (D), and phase angle (theta).
