Keywords

What is a superior Q factor?
In a nutshell, a capacitor's Quality factor is an indicator of low loss.
The energy loss in a capacitor is called the dielectric tangent, and the inverse of that dielectric tangent is the Q factor.
In other words, low loss = high Q factor = good capacitor performance.

Data is based on research by Kyocera.
