Quality Factor (Q) vs Inductance
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.
Example Calculation
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
