It's lot easier and quicker to bread-board a circuit in LTSpice than it
is to wire up a test circuit, but what that means is that you need to
make fewer real circuits and they are a lot more likely to work when tested.

All it explains is boeings falling apart and astronuts ending up stuck at the ISS

John Larkin's simulated inductors tend not to have any parallel capacitance.

The trick is to know when it matters. ESR and core loss are usually
more important.

I designed this surface-mount inductor for my Pockels Cell driver,
after several tries using commercial parts. They all smoked.

It's wound on a specially marked Sharpie pen that we have carefully
reserved.

The grey gap-pad gives it some extra cooling. The board has lots of
thermal vias down to the water-cooled baseplate.
