SURFACE-MOUNT FUSES
Pulse Tolerant Chip Fuses
Pulse Tolerant Chip Fuses have high inrush current
withstand capability and provide overcurrent protection
for DC power systems. These devices combine a silver
fusing element and monolithic, multilayer design to
provide strong arc suppression characteristics.
These
RoHS-compliant
surface-mount
devices
can
help facilitate the development of more reliable, high-
performance consumer electronics such as laptops,
multimedia devices, cell phones and other portable
electronics.
