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 fuses 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 Game systems Lead-free and RoHS compliant LCD monitors Halogen free (refers to: Br900ppm, Cl900ppm, Br+Cl1500ppm) Scanners Monolithic, multilayer design High-temperature performance -55C to +125C operating temperature range RoHS Compliant, ELV Compliant Halogen Free Specifications subject to change without notice. 2016 Littelfuse, Inc. 89 HFSurface Mount Fuses Fast-Acting Chip Fuses Table FF1 Clear Time Characteristics % of Rated Current Clear Time at 25C 100% 4 hrs (min) 250% 5 s (max) 400% 0.05 s (max) Table FF2 Shape and T0.0200.0ypical Electrical Characteristics, Dimensions and R04 ecommended 0.0390.004 (0.510.10) (1.000.10) Dimensions in (mm) Pad Layout Shape and 0.0200.004 0.0390.004 (0.510.10) 0.0200.004 Dimensions (1.000.10) 0402 (1005mm) Fast-Acting Chip Fuses (0.510.10) in (mm) Typical Electrical Characteristics Max Interrupt Ratings Shape and 0.0200.00.0100.004 04 0.0390.004 Rated Nominal Nominal 0.0200.004 (0.510.1(0.250.10) 0) Dimensions (1.000.10) (0.510.10) 2 Current Cold DCR I t Voltage Current in (mm) 2 Part Number (A) ( )* (A sec) (V ) (A) DC 0.0100.004 0.063 Recommended 0.0200.004 (0.250.10) (1.60) Pad Layout (0.510.10) 0402SFF100F/24 1.00 0.120 0.0170 24 35 0.016 in (mm) (0.40) 0402SFF150F/24 1.50 0.056 0.0490 24 35 0.0100.004 Recommended 0.063 (0.250.10) (1.60) Pad Layout 0402SFF200F/24 2.00 0.035 0.0700 24 35 0.028 0.016 in (mm) (0.70) (0.40) 0402SFF300F/24 3.00 0.021 0.1250 24 35 Recommended 0.063 (1.60) Pad Layout 0.024 0402SFF400F/24 4.00 0.014 0.2250 24 35 0.028 (0.60) 0.016 in (mm) (0.70) (0.40) 0.024 0.028 (0.60) (0.70) 0.024 (0.60) Shape and 0.0310.006 0.0630.006 (0.800.15) 0603 (1608mm) Fast-Acting Chip FusesDimensions (1.600.15) Typical Electrical Characteristics Max Interrupt Ratings in (mm) Shape and 0.0310.006 Rated Nominal Nominal (0.800.15) 0.0630.006 Dimensions 2 Current Cold DCR I t Voltage Current (1.600.15) 0.0310.006 in (mm) 2 (0.800.15) Part Number (A) ( )* (A sec) (V ) (A) DC Shape and 0.0310.006 (0.800.15) 0.0630.006 0603SFF050F/32 0.50 0.485 0.0029 63 35 Dimensions (1.600.15) 0.0310.006 in (mm) 0.0140.006 (0.800.15) 0603SFF075F/32 0.75 0.254 0.0064 63 35 (0.360.15) 0603SFF100F/32 1.00 0.147 0.0160 63 35 0.0310.006 0.0140.00.11006 Recommended 0603SFF150F/32 1.50 0.059 0.0300 63 35 (0.800.15) (0.360.1(2.80)5) Pad Layout 0603SFF200F/32 2.00 0.044 0.0600 32 35 0.024 in (mm) (0.60) Recommended 0.0140.00.11006 0603SFF250F/32 2.50 0.032 0.1150 32 35 (0.360.1(2.80)5) Pad Layout 0603SFF300F/32 3.00 0.025 0.1900 32 35 0.039 0.024 in (mm) (1.00) (0.60) Recommended 0.110 0603SFF350F/32 3.50 0.024 0.2950 32 35 (2.80) Pad Layout 0.043 0.039 0603SFF400F/32 4.00 0.018 0.4000 32 35 (1.09) 0.024 in (mm) (1.00) (0.60) 0603SFF500F/32 5.00 0.013 0.7000 32 35 0.043 0603SFF600F/24 6.00 0.010 1.1250 24 35 0.039 (1.09) (1.00) 0.043 1206 (3216mm) Fast-Acting Chip Fuses(1.09) Typical Electrical Characteristics Max Interrupt Ratings Rated Nominal Nominal Shape and 0.0630.008 2 Current Cold DCR I t Voltage Current Dimensions (1.600.20) 0.1260.008 2 Part Number (A) ( )* (A sec) (V ) (A) in (mm) DC (3.200.20) Shape and 0.0630.008 1206SFF050F/63 0.50 0.730 0.0021 63 50 Dimensions (1.600.20) 0.1260.008 1206SFF075F/63 0.75 0.513 0.0052 63 50 in (mm) (3.200.20) Shape and 1206SFF100F/63 1.00 0.220 0.0120 63 50 0.0630.008 Dimensions (1.600.20) 0.1260.008 0.0430.008 1206SFF150F/63 1.50 0.120 0.0250 63 50 in (mm) (3.200.20) (1.100.20) 1206SFF175F/63 1.75 0.100 0.0450 63 50 1206SFF200F/63 2.00 0.050 0.0700 63 50 0.0430.008 (1.100.20) 1206SFF250F/32 2.50 0.035 0.1400 32 50 0.0200.010 (0.510.25) 1206SFF300F/32 3.00 0.031 0.2200 32 50 0.0430.008 (1.100.20) 1206SFF400F/32 4.00 0.022 0.3800 32 45 0.0200.010 Recommended 0.173 1206SFF500F/32 5.00 0.015 0.6000 32 45 (0.510.25) (4.40) Pad Layout 0.059 1206SFF600F/32 6.00 0.013 1.0000 32 50 in (mm) (1.50) Recommended 0.10.0200.073 10 1206SFF700F/32 7.00 0.011 1.7500 32 50 (4.40)(0.510.25) Pad Layout 0.071 1206SFF800F/32 8.00 0.008 2.5000 32 50 in (mm) 0.059 (1.80) (1.50) Recommended 0.173 1206SFF600F/24 6.00 0.013 1.0000 24 45 (4.40) Pad Layout 0.057 1206SFF700F/24 7.00 0.011 1.7500 24 45 0.071 in (mm) (1.45) 0.059 (1.80) (1.50) 1206SFF800F/24 8.00 0.008 2.5000 24 45 0.057 * Measured at 10% of rated current and 25C ambient temperature. 0.071 (1.45) 2 (1.80) Melting I t at 0.001 sec clear time. 0.057 (1.45) 90 Specifications subject to change without notice. 2016 Littelfuse, Inc.
