For components, the quality factor (Q) serves as a measurement of the
reactance purity. In the real world, there is always some associated resistance
that dissipates power, decreasing the amount of energy that can be
recovered. The quality factor can be defined as the ratio of the stored energy
(reactance) and the dissipated energy (resistance). Q is generally associated
with inductors and D (dissipation factor) for capacitors. Below shows the
relationships between these parameters:
