Surface Mount Fuses NANO2® > 157 Fuse and Holder Combination 157 Series – Standard Nano2® Fuse and Clip Assembly PS E RoHS Description The 157 Series – Standard Nano Fuse/Clip assembly is a small, square, very fast acting surface mount fuse that is assembled in surface mountable fuse clips. The fuse clip and pre-installed fuse combination can be automatically placed in PC Board in one efficient manufacturing operation. It permits quick and easy replacement of fuses without performing desoldering process, even in the field and without exposing the PC Board to detrimental effects of rework solder heat.
