Reactance
Estimate capacitive and inductive reactance at any frequency.
Applies Xc = 1/(2πfC) and Xl = 2πfL so you can gauge filter corners, matching networks, and impedance vs. frequency.

Quick presets
Reactance plots help pick filter components before running full SPICE sweeps.
Inputs
Filter planning
Match Xc and Xl to locate resonance (Xc = Xl). Use the tool to sweep frequencies before running SPICE.
Layout cue
Reactance magnitudes hint at how sensitive nodes are to stray inductance/capacitance—guide placement accordingly.
Design notes
- Keep an eye on tolerance: ±10% inductors swing reactance significantly at high frequencies.
- Use reactance to judge whether parasitics dominate. If stray capacitance is comparable to calculated C, adjust the design.
- Combine this with the decibel calculator to translate reactance ratios into attenuation at the cutoff.
