Formula and methodology
Formula: Ideal characteristic impedance Z₀ = √(L′/C′) after converting microhenries and picofarads to SI units.
The lossless transmission-line relation connects distributed inductance and capacitance rather than lumped component values.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Inductance per length — µH/m; minimum 1.0E-6; maximum 1000000
- Capacitance per length — pF/m; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Inductance per length | 0.25 |
| Capacitance per length | 100 |
Characteristic impedance ≈ 50 Ω.
Assumptions and limits
- Inductance and capacitance per length are positive and use the displayed units.
- The line is treated as uniform, lossless, and sufficiently long for the ideal relation.
- Resistance, conductance, frequency dependence, connectors, and geometry are not modeled.
