Nano2 > 157T Fuse and Holder Combination
0157T Series – Standard Nano Fuse Clip
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 efcient
manufacturing operation. It permits quick and easy
replacement of fuses without performing desoldering
process, even in the eld and without exposing the PC
Board to detrimental effects of rework solder heat.
