Reactance — common cases, pre-computed
Capacitive (Xc) and inductive (Xl) reactance for the most common frequency / component combinations, computed for ideal parts. Need a different value? Open the interactive calculator.
Capacitive reactance (Xc = 1 / 2πfC)
Inductive reactance (Xl = 2πfL)
Values are ideal-component reference estimates (no parasitics) — confirm against the part datasheet, especially near self-resonance.
