Resonant Frequency

LC Resonance Formula

f = 1 / (2π × √(L × C))

Where f = frequency (Hz), L = inductance (H), C = capacitance (F).

Applications

  • LC Oscillators — Radio transmit/receive resonant circuits
  • Filter Design — Band-pass, band-stop filters
  • Wireless Charging — Resonant inductive coupling
  • Impedance Matching — LC matching networks in RF circuits
