Quality Factor (Q) vs Inductance
Formula
## Quality Factor (Q) **Q = (1/R) x sqrt(L/C)** Also: **Q = f_0 / Bandwidth** Higher Q means less energy loss, sharper resonance, and narrower bandwidth.
Esempio Risolto
100 uH, 100 pF, 5 ohms series resistance.
- 01sqrt(L/C) = sqrt(0.0001 / 1e-10) = sqrt(1e6) = 1000
- 02Q = 1000 / 5 = 200
- 03f_0 = 1.59 MHz, BW = 7958 Hz

What is a good Q value?
Depends on application. RF filters often need Q > 100. Audio filters may use Q of 1-10.
What limits Q in practice?
Component losses: inductor wire resistance, capacitor ESR, and radiation losses.
Q of a single component?
For an inductor: Q = XL/R. For a capacitor: Q = 1/(2pi x f x C x ESR).
