Description
The 466 Series Fast-Acting Surface Mount Fuse (SMF)
is a small (1206 size) thin-film device designed for
secondary protection of circuits used in space constrained
applications such as hand-held portable electronic devices.
This series is 100% lead-free and meets the requirements
of the RoHS directive. New Halide-Free 466 Series fuses
are available–to order use the “HF” suffix. See Part
Numbering section for additional information.
