摘要：
An improved electrical fuse having axial leads (5) and comprising a fuse wire in a cylindrical sleeve (2) supported at its ends by lead carrying end caps (3) is coated over the length of the fuse body by an adherent insulating layer of plastic (7). Improved humidity resistance and mechanical strength are achieved and control of coating thickness is improved. Use of hot plastic for the adherent insulating layer (7) reflows solder joint (4) reducing instances of open or high resistance fuses which must be rejected. Also, the i.sup.2 t performance is significantly improved over other adherent coatings.
