ℓ : Length of the coil (mm). Equal to c x N.
Calculated parameters:
-
+ Frequency independent:
- L : Inductance is calculated using Nagaoka's equation incorporating his coefficient.
- C : Capacitance is calculated using Knight's 2016 paper on self-resonance and self-capacitance of solenoid coils.
- Rdc : DC resistance is calculated using conductor length divided by the conductor cross-sectional area, assuming a copper conductor.
- SRF : Self-resonant frequency (MHz) for the unloaded coil.
- - Xₗ : Inductive reactance at the given frequency. (Ω)
- - |Z| : Impedance at the given frequency. (Ω)
+ - wire : Length of wire required to wind the inductor.
+
+ Frequency dependent: (Text goes RED when selected frequency > SRF. Inductor model is not accurate once SRF is exceeded.)
+ - f : Selected frequency in MHz
- δ : Skin depth due to skin effect (μm)
- Rac : AC resistance is calculated using the skin effect and proximity resistance from empirical data collected by Medhurst using the spacing ratio, and length-to-diameter ratio.
- - Q : Quality factor of device, based on reactance (X) ÷ resistance (Rac) at the given frequency.
+ - Xₗ : Inductive reactance at the given frequency. (Ω)
+ - Z : Complex impedance at the given frequency. (Ω)
+ - |Z| : Impedance magnitude at the given frequency. (Ω)
+ - Q : Effective Quality Factor of the inductor at the given frequency. (|Z.im|/Z.re)
