🎛️ Passive LC Filters (5th / 7th Harmonic LC Trap Filters, Tuned fn = 4.7 x f1, Q Factor 30-60)

Passive Tuned Harmonic Filter Calculator

Size passive single-tuned LC bandpass trap filters ($f_n = rac{1}{2 pi sqrt{L C}}$ tuned to 4.7th harmonic at 282 Hz or 6.7th harmonic at 402 Hz to prevent grid parallel anti-resonance): calculate reactor tuning inductive reactance ($X_L$), capacitor kVAR bank rating, Quality Factor ($Q = X_L / R = 30 ext{ to }60$), and industrial harmonic profits.
