Find the resonant frequency of an LC tank circuit from the inductance and capacitance, or solve for a component to tune to a target frequency.
An inductor and capacitor together resonate at f = 1 / (2π·√(L·C)). This is the basis of radio tuning, oscillators and filters. Increasing either L or C lowers the resonant frequency.
An inductor and capacitor exchange energy back and forth, and at one particular frequency they reinforce each other: the resonant frequency, f = 1 / (2π·√(L·C)). It is how radios tune to a station and how many oscillators set their frequency.
Inductance in microhenries (µH) and capacitance in picofarads (pF), which are the practical ranges for radio-frequency work. The tool converts internally and shows the frequency in Hz up to GHz.
Pick one component you have, then adjust the other until the resonant frequency matches your target. Larger L or C gives a lower frequency, smaller gives higher.
