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.
