AVX: Parasitics & Capacitor Selection, Part 5: Q

In part 4A of this series, which examined dissipation factor (DF), I mentioned that the Q of a capacitor is the reciprocal of its DF. So, like DF, Q is a dimensionless number. It represents the ratio of the maximum energy stored to the power loss in a system at a given angular frequency rather than the inverse (DF).
