Fuse Datasheet 467 Series 0603 Fast-Acting Fuse RoHS Pb Description The 467 Series Fast-Acting Surface Mount Fuse (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 availableto order use the HF suffix. See Part Numbering section for additional information.. Features & Benefits Compatible with lead-free Element covering material is solders and higher temperature resistant to industry standard profiles cleaning operations High performance materials Mounting pad and electrical provide improved performance performance is identical to in elevated ambient Littelfuse 431 and 434 Series temperature applications products Halogen free, Lead-free and Mark ed on top surface with code to allow amp rating RoHS compliant Additional Information identification without testing Recognized to UL/CSA/NMX Low profile for height sensitive 248-1 and UL/CSA/NMX 248-14 applications Flat top surface for pick-and- place operations Applications Resources Accessories Samples Secondary protection for space constrained applications: Cell phones D VD players B atter y packs Hard disk drives.

Rerating depicted in this curve is in addition to the standard derating of 25% for continuous operation. 0.1 Example: For continuous operation at 70 degrees celsius, the fuse should be deratedas follows: I = (0.75)(0.80)I = (0.60)I RAT RAT 2. The temperature derating curve represents the nominal conditions.
