� � «Use pin»
If the box is checked, the coupling factor is defined by the quantity connected to the pin, otherwise
the value in the text box is used.

The component represents a transformer based on the Spiro model. For each coil make sure a
network path exists to the ground node. The macro does not permit an access to the initial
value of currents, these are assumed to be zero. Within the dialog you can define the main and
leakage inductances, the equivalent resistances for iron losses and the winding resistances
for each side.
