- In KiCAD EESchema place suitable symbol. Note the pin numbers for use in the subcircuit model.
2. In a text editor create a SPICE model like this:
L1 1 2 130u means an inductor of 130 uH between pins 1 and 2. The turns ratio is the square of the inductance ratio of the coils. K1 is the coupling f actor shown here as 1 being perfect. See this LT Spice article. The series resistance did not have the expected behaviour so I removed them.
3. Double click on the symbol and enter the properties as shown in the picture below.
