Although many High-Q capacitors are available on the market their performance can vary widely depending on design and the quality of manufacturing, as Scott Horton of Johanson Technology explains to ...

When simulating a circuit structure it is crucial to be able to account for parasitics or non-ideal behavior of components such as non-linear quality factor (Q-value) and parasitic package capacitance ...

Exxelia’s CH series of surface-mount ceramic capacitors are designed with high Q-factor and stable operation for rf applications in medical MRI scanners, scientific, industrial and cellular base ...

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 ...
