a completely new multi-stage high voltage treatment process for the lowest noise floorNoise floor in a fuse? That is probably the thing that has to be explained.
We've seen some fuses that have a Teflon or similar sleeve around the fuse element, possibly meant to keep it from vibrating (if you watch a fuse as it sits in an amplifier circuit, you can see it move from the current flow through it). The problem with this is when the current of the element is exceeded, the metal is supposed to get white hot and fail- but the Teflon tube keeps it in place, allowing current to continue to flow. This can result in a plasma state, not really what you want a fuse to do at all!
