467 Series Fuse
Description
The 467 Series Fast-Acting SMF is an ultra small (0603
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 467 Series fuses are
available–to order use the “HF” suffix. See Part Numbering
section for additional information..

Temperature Rerating Curve
Note:
1. Derating depicted in this curve is in addition to the standard derating of 25% for
continuous operation.
Example:
For continuous operation at 70 degrees celsius, the fuse should be deratedas follows:
I = (0.75)(0.80)I
2. The temperature derating curve represents the nominal conditions. For questions
about temperature derating curve, please consult Littelfuse technical support
for assistance.
