Surface Mount Fuses

NANO^2®> 157T Fuse and Holder Combination

157T Series – Standard Nano^2®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.
