Hi Stefan, I think the problem are the airgaps between the cores. Perhaps you´ll get a little better result if you grind down the coatings at the inner front ends of the cores. Although its nearly im
Hi Clemens, I have measured a big air core coil of approx. 3.37mH - once w/o ferrites inside - once with two identical ferrite cores (µi about 125) spaced by 2cm - once with one core of the same type
