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.  
Features & Benefits  
■ Surface Mountable  
■ Easily replaceable on PC Board  
(Field Replaceable)  
■ Very Fast-Acting Fuse  
■ RoHS compliant and Halogen  
Free  
■ Fully compatible with RoHS/  
Pb-Free solder alloys and  
higher temperature profiles  
associated with leadfree  
assembly.  
■ Available in ratings of 0.062 ~  
10 Amperes.
