Calculate inductance, inductive reactance, capacitive reactance, impedance, admittance, susceptance, conductance, and AC circuit parameters for electrical and electronic applications.
RF Inductor Check
Enter an inductor value in nH and frequency in GHz to quickly estimate inductive reactance in ohms.
Reverse Calculation
If you know target reactance at a frequency, choose R Reactance mode to calculate the required inductance.
This original SVG shows an RF inductor model where inductance creates frequency-dependent reactance and admittance.
This CalcBoy calculator helps convert between inductor value and frequency-dependent reactance using a lightweight RF design workflow.
Inductive reactance changes with frequency, so the same inductor can behave very differently at low frequency, RF frequency and microwave frequency. A small nH inductor may look almost like a wire at low frequency, but it can create meaningful impedance at GHz frequencies. This Inductance & Reactance & Admittance Calculator is useful when checking RF matching networks, PCB inductors, bias chokes, impedance paths, and quick high-frequency design estimates.
Inductive reactance is the opposition an inductor provides to AC current. It increases as frequency increases.
The calculator uses Reactance = 2πfL and Inductance = X / (2πf), preserving the original calculator logic.
nH is common in RF and microwave circuits where inductors are often very small.
Yes. Select MHz in the frequency unit selector. The code converts it using the original multiplier.
Admittance is calculated as 1000 divided by reactance in the original calculator format.
No. This is a simplified ideal inductor calculation and does not include self-resonant frequency or parasitic effects.
Yes, it is useful for quick estimates in RF matching and impedance network design.
Because inductive reactance is directly proportional to frequency and inductance.
