Description
The RoHS compliant 154 Series OMNI-BLOK® Fuse and
Holder Assembly offers a solution for efficient installation
and easy replacement of miniature Nano2® surface
mount fuses. Offered in a tape and reel package, this
fuse and holder combination can be installed on a PC
board as an efficient single step. Fuse replacement can
be accomplished without exposing the PC board to the
detrimental effects of solder heat.
