[0036] Example: A surface mount fuse, as attached Figure 1-13 As shown, it includes a fuse chip 1. This fuse chip 1 is mainly composed of two terminal electrodes 2, a ceramic substrate 3, a melt layer 4, an arc-extinguishing glass layer 5 and a protective layer 15. The melt layer 4 is located on the ceramic substrate. On the upper surface of the sheet 3, the two terminal electrodes 2 are located on both sides of the melt layer 4 and are electrically connected to the melt layer 4, and the arc-extinguishing glass layer 5 covers the melt layer 4 and the terminal electrodes 2 The area near the melt layer also includes a fuse body 7 with a circular through hole 6 in the middle, the fuse chip 1 is located in the circular through hole 6 of the fuse body 7, and two metal covers 8 are respectively located in the Two ends of the fuse body 7 are cut off and the circular through hole 6 is covered to form a closed cavity, and the terminal electrode 2 is electrically connected to the metal...
