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).

Electrostatic Capacitance Element And Resonance Circuit

A capacitance element body 2 is configured by two or more capacitors, the capacitors being formed of a dielectric layer 3 and at least three internal electrodes, the internal electrodes each being laminated via the dielectric layer 3 and arranged to allow a center of gravity of an electrode body forming electrostatic capacitance to be arranged on a straight line in a lamination direction.
