SURFACE-MOUNT FUSES Fast-Acting Chip Fuses Fast-acting chip fuses help provide overcurrent protection for systems using DC power sources up to 63V . The fuse’s monolithic, multilayer design helps DC provide the highest hold current in the smallest footprint, reduce diffusion-related aging, improve product reliability and resilience, and enhance high-temperature performance in a wide range of circuit designs. These RoHS-compliant surface-mount devices offer strong arc suppression characteristics and help facilitate the development of more reliable, high-performance consumer electronics such as laptops, multimedia devices, cell phones and other portable electronics. BENEFITS APPLICATIONS • Small size with high current ratings • Laptops • Temperature stability • Digital cameras • High reliability and resilience • Cell phones • Strong arc suppression characteristics • Printers • DVD players FEATURES • Portable electronics • Lead-free and RoHS compliant • Game systems • Halogen free • LCD monitors (refers to: Br900ppm, Cl900ppm, Br+Cl1500ppm) • Scanners • Monolithic, multilayer design • High-temperature performance • -55°C to +125°C operating temperature range RoHS Compliant, ELV Compliant HF Halogen Free Specifications subject to change without notice. ©2016 Littelfuse, Inc. 89
