Fuse Datasheet 468 Series 1206 Slo-Blo® Fuse RoHS Pb Description The 468 Series Slo-Blo® 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 468 Series fuses are available– to order use the “HF” suffix. See Part Numbering section for additional information. Features and Benefits Additional Information Resources Accessories ■ Complies with electronic industry environmental standards for lead reduction. ■ Package is visually distinct from fast-acting version for easy identification. ■ Product is compatible with lead-free solders and higher temperature profiles. ■ Top side marking allows visual verification of amperage rating. ■ Time delay feature withstands high inrush currents and prevents nuisance openings. ■ Lead-free, halogen-free and ROHS compliant. Applications Samples Secondary protection for space constrained applications: Electrical Characteristics for Series ■ Cell phones ■ DVD players ■ Battery packs ■ Hard disk drives. ■ Digital cameras % of Ampere Rating Opening Time at 25OC 100% 4 hours, Minimum 200% 1 sec., Min.; 120 sec., Max.

Rerating 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)IRAT = (0.60)IRAT 0.01 2.
