Description
The 468 series fast-acting surface mount fuse series is
an ultra small (EIA 0402) thin-film device designed for
secondary protection of circuits used in space constrained
applicaitons such as hand-held and portable electronic
devices.
This series of devices are 100% lead-free and meet the
requirements of the RoHS directive.
