## 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.

Note:
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:
- I = (0.75)(0.80)IRAT = (0.60)IRAT
2. The temperature derating curve represents the nominal conditions. For questions about temperature derating curve, please consult Littelfuse technical support for assistance.
