Also, the default unit of measurement for LTSPICE inductors is the Henry. This is true whether the inductor is a choke or a transformer winding coupled to another winding. When the inductor is a transformer winding, the ratio between coupled windings is expressed by assigning them specific values of inductance. The assigned inductance ratio acts similarly to ratios of impedance. In other words, a transformer with an 8K primary Z and 800 ohm secondary Z can be simulated with a 10H primary and 1H secondary. This ratio will relate to the turns ratio (voltage ratio) in the same way as any transformer.
