Standard Nano^2®Fuse and Clip Assembly

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.
