Surface Mount Fuses  
NANO> 157T Fuse and Holder Combination  
157T Series – Standard Nano2® Fuse and Clip Assembly

RoHS  
Description  
The 157T Series Fuse/Clip assembly is a small, square,  
Time-Lag, surface mount fuse that is assembled in surface  
mountable fuse clips. The unique time delay feature of this  
fuse design helps solve the problem of nuisance opening”  
by accommodating inrush currents that normally cause a  
fast acting fuse to open.  
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.
