TOOL 01 / LC RESONANCE

LC resonance calculator

Enter an inductance and a capacitance, and the resonant frequency follows.

Resonant frequency

—MHz

Angular frequency ω

This assumes an ideal LC tank: no parasitic resistance or capacitance, and no load. In a real circuit, Q, parasitics, and the test fixture all pull the centre frequency away from this number.

f₀ = 1 / (2π · √(L · C))
