Solve for frequency
5.033 MHz

Calculation steps

  1. 1f = 1 / (2π√(LC)) = 1 / (2π × √(10μH × 100pF))
  2. 2L·C = 1.000e-15 s² → √(LC) = 3.162e-8 s
  3. 3f = 5.033 MHz

Typical LC combinations

AM radio (MW)200 μH + 360 pF → ~593 kHz
FM radio0.1 μH + 25 pF → ~100 MHz
50 Hz notch10 H + 1 μF → ~50 Hz
SMPS filter10 μH + 100 μF → ~5 kHz
Crystal load16 MHz + 2×22 pF 负载电容
At resonance the ideal LC tank has infinite impedance (parallel) or zero (series) — real circuits are limited by Q = (1/R)·√(L/C), so low-loss coils and NP0/C0G capacitors give sharper selectivity. Parasitics dominate above ~100 MHz: every capacitor has self-resonance from its lead inductance. For a desired f, picking L and C is a trade: larger L/C ratio raises Q but makes tuning coarser.
