This position should not be filled with a wire-wound component.
Metal glaze, at certain values and body sizes, offers a reduced self
inductance, allowing them to function in higher frequency snubber
circuitry.

Yes, I'm aware of the perils of parasitic inductance in w/w resistors;
the one I've selected doesn't suffer from it.

Unless you've actually cracked one open, you will not be able to tell
what the element construction is.
