Fuse Datasheet 157 Series Standard Nano2® Fuse and Clip Assembly RoHS PS E 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. Features & Benefits ■ Surface Mountable ■ Very Fast-Acting Fuse ■ Fully compatible with RoHS/ Pb-Free solder alloys and higher temperature profiles associated with leadfree assembly. Additional Information ■ Easily replaceable on PC Board (Field Replaceable) ■ RoHS compliant and Halogen Free ■ Available in ratings of 0.062 ~ 10 Amperes. Applications ■ Instrumentation ■ Telecommunications ■ Base Stations Electrical Characteristics for Series Resources Accessories Samples % of Ampere Rating Opening Time at 25ºC 100% 200% 4 hours Minimum 5 secs.
