I continue to wonder HOW SR fuses do whatever they are claimed to do. I realize that to the SR faithful this question is blasphemy, and to even raise this question often engenders the ire of the Magic Fuse Faithful, but since this question has never been answered, I still wonder. I'm not contacting SR because I'm more interested in what the SR fuse users, or "Fusers," think the answer might be. Massaged electrons? Current being passed along to the circuits with a light coating of sauce? SR claims to zap the fuses with a zillion volts or something, and puts graphene someplace, but I still wonder how they arrived at this technology, and why? Also, why can't they produce a product that conforms to existing standards of use (like my 2 dollar Littlefuse products do) if they're sophisticated enough to manufacture them in the first place? Note this post doesn't need to be read carefully the first time as geoffkait will repost it in his response. Thanks is advance for the kind and well considered answers to my query.
