The 468 Series Slo-Blo
®
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 Halogen-Free 468 Series
fuses are available–to order use the “HF” suffix. See Part
Numbering section for additional information.
• Cell phones
• Battery packs
• Digital cameras
• DVD players
• Hard disk drives.
Secondary protection for space constrained applications:
. Application testing is strongly recommended.
