SMD Thin-Film Fuse
ACCU-GUARD
®
TECHNOLOGY
The Accu-Guard
®
series of fuses is based on thin-film tech-
niques. This technology provides a level of control on the com-
ponent electrical and physical characteristics that is generally
not possible with standard fuse technologies. This has allowed
AVX to offer a series of devices which are designed for mod-
ern surface mount circuit boards which require protection.

Miniature 0402 and 0603 Size Thin-Film Fuses
The new F0402G and F0603G 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 compact 0402 and 0603 packages and features
LGA terminations.
