Q or quality factor represents the efficiency of a capacitor. It is the ratio of energy stored in a capacitor to the energy dissipated as thermal losses due to the equivalent series resistance (ESR) and I2R losses. Higher ESR can cause excessive heating in the capacitor at higher frequencies beyond its max allowable power dissipation. Since Q is inversely proportional to …
