In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Q factor is alternatively defined as the ratio of a resonator''s centre frequency to its bandwidth when subject to an oscill…

Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
Decoupling capacitors selection algorithm based on maximum anti-resonance points and quality factor of capacitor
A decoupling capacitors (decaps) selection algorithm based on maximum anti-resonance points of the power distribution network and the quality factor (Q) of the capacitor is proposed. The experimental results show that the proposed algorithm is superior to the fast algorithm regarding the number of consuming decaps and the genetic …

Quality Factor of a Capacitor in typical applications
The Quality (Q) Factor of a capacitor is a unitless value which is equal to the capacitor''s reactance divided by the Equivalent Series Resistance (ESR) of the capacitor. As both reactance and ESR vary with changes in frequency, the Q value of a capacitor will also vary greatly with changes in frequency. Most applications do not have …

Each capacitor is designed for a particular rated voltage, which it must stand up to without adverse effect during continuous operation. However, this only applies to ambient temperatures of < +85 C; at higher temperatures the maximum permissible voltage or voltage limit for continuous operation is reduced by voltage derating. ...
How can I accurately measure the quality factor (Q)? | FAQ
The quality factor is a measure of the extent to which a capacitor acts like a theoretically pure capacitor6. It is the inverse of the dissipation factor (DF). Q is typically reported for …
Choosing and Using Bypass Capacitors (Part 3 of 3)
