I have some non-inductive wirewound resistors. They
simply reverse the direction of the winding every
so often to obtain canceling fields.

Has anyone actually tested those over a wide frequency range? I've
always considered them a witches brew of parasitic capacitance, stray
coupling between segments and who knows what else.
On the other hand, maybe they got it just right.

I have always thought of them as noninductive at audio frequencies. Much
less as the frequency goes up.
