Surface Mount Fuses
154/154T/154L/154TL Series OMNI-BLOK® Fuse and Holder Assembly
Description
The RoHS compliant 154 Series OMNI-BLOK® Fuse and
Holder Assembly offers a solution for efficient installation
and easy replacement of miniature Nano 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.
The fuse holder unit may be sold as a stand-alone item,
shipped in bulk quantity using part number 01550900M
and also pre-packaged in tape and reel cartridges using part
number 01550900DR.
