description The invention relates to the technical field of fuses, in particular to a surface-mounted fuse which comprises an insulating shell and a metal melt, side edge cavities and an inner table are arranged in the insulating shell, the side edge cavities are arranged at the two ends of the inner table, narrow and thin cavities are formed in the inner table and communicated with the side edge cavities, and the sectional area of the side edge cavities is larger than that of the narrow and thin cavities; the metal melt is arranged in the narrow and thin cavity in a penetrating mode, and the two ends of the metal melt are arranged in the side edge cavities. The surface-mounted fuse has the advantages of high breaking capacity, lead-free design, simple production process, low cost and the like. According to the design of the insulating shell, the rapid cooling effect of high thermal conductivity of quartz sand on electric arcs is introduced, and the mechanical strength of the shell is improved through the middle wall thi
