Gentle rolloff, baby!

@phos a central gap also likes to cook the innermost windings @_@

@phos do you profile your cores?

@RueNahcMohr nah I mostly went by datasheet and calculation in the case of gapped ferrite. For example this one has a pretty gentle roll off https://www.mag-inc.com/Media/Magnetics/Datasheets/00K6527E060.pdf

@RueNahcMohr I will have to probably build or get some kind of saturation tester at some point for a clear pass fail at least… or maybe build an automated profiling test rig that measures the inductance at different biases, not the worst idea

@RueNahcMohr but with such a gentle roll off I could go 15A over current and it would still not saturate fully, so the exact profile isn’t important as long as it meets my pretty loose requirements
