Inductor Q Factor Calculator

The Quality (Q) factor of an inductor is a measure of how close the inductor is to an ideal inductor i.e. one that has no parasitic resistance.

Enter Frequency, Inductance and Internal Resistance of the Inductor to calculate the Quality Factor.

  • Frequency (f)
  • Inductance (L)
  • Internal Resistance (R)
