Accu-Guard® II Low Current
Miniature 0402 Size Thin-Film Fuses
The new F0402G Accu-Guard® series of fuses is based on
thin-film technology which allows precise control of the
component electrical and physical characteristics that is not
possible with standard fuse technologies. The Accu-Guard
Low Current series encompasses the lowest current ratings
in a compact 0402 package and features LGA terminations.
