466 Series Fuse
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 Halogen-Free 466 Series
fuses are available to order using the “HF” suffix. See Part
Numbering section for additional information.

1. Rerating depicted in this curve is in addition to the standard rerating of 25% for
continuous operation.
Example:
For continuous operation at 70 degrees celsius, the fuse should be rerated as follows:
