* Inductor SPICE subcircuit
|
|
* Model with DC resistance and parasitic parallel capacitance
|
|
*
|
|
* Equivalent circuit:
|
|
*
|
|
* ┌─── Cp ───┐
|
|
* 1 ── Rdc ──┤ ├── 2
|
|
* └─── L ────┘
|
|
*
|
|
* Behavior:
|
|
* DC: Z ≈ Rdc (small winding resistance)
|
|
* f < SRF: Z dominated by L (inductive, |Z| rises with f)
|
|
* f = SRF: Parallel resonance of L and Cp, impedance peaks
|
|
* f > SRF: Z dominated by Cp (capacitive, |Z| falls with f)
|
|
*
|
|
* Parameters:
|
|
* LVAL - Inductance value in henries
|
|
* RDC - DC winding resistance (ohms)
|
|
* CP - Parasitic parallel capacitance (farads)
