SURFACE-MOUNT FUSES High-Current-Rated Chip Fuses The monolithic multilayer design of the Littelfuse high-current- rated chip fuses helps to provide some of the highest current ratings available in the 1206 size and enhances high-temperature performance in a wide range of circuit protection designs. The devices small size, high reliability and strong arc suppression characteristics make them suitable for overcurrent protection of power supplies, servers, communications equipment, voltage regulator modules, and other high current, small size applications. BENEFITS APPLICATIONS Glass ceramic monolithic structure provides stability Communications equipment in application cycling Voltage regulator modules High-current rating in a small package allows more Power supplies efficient use in system space Servers Strong arc suppression in overcurrent conditions FEATURES Lead-free materials and RoHS compliant Halogen free (refers to: Br 900ppm, Cl 900ppm, Br+Cl 1500ppm) Monolithic multilayer design High-temperature performance -55C to +150C operating temperature range RoHS Compliant, ELV Compliant Halogen Free Specifications subject to change without notice. 2016 Littelfuse, Inc. 105 HFSurface Mount Fuses Pulse Tolerant Chip Fuses Table FH1 Clear Time Characteristics 1206SFH Series % of Rated Current Clear Time at 25C 100% 4 hrs (min) 250% (10-20A) 5 s (max) 350% (25-30A) 5 s (max) Table FH2 Typical Electrical Characteristics, Dimensions and Recommended Pad Layout 1206 (3216mm) High-Current-Rated Chip Fuses Typical Max Electrical Characteristics Interrupt Ratings Shape and 0.0630.008 Dimensions (1.600.20) Rated Nominal Nominal 0.1260.008 in (mm) (3.200.20) 2 Current Cold DCR I t Voltage Current 2 Part Number (A) ( )* (A sec) (V ) (A) DC 1206SFH100F/24 10 0.010 9 24 100 1206SFH120F/24 12 0.008 14 24 100 0.0380.008 (0.970.20) 1206SFH150F/24 15 0.005 26 24 100 1206SFH200F/24 20 0.003 56 24 100 1206SFH250F/24 25 0.0016 187 24 250 0.0200.010 (0.510.25) 1206SFH300F/24 30 0.0012 270 24 300 Recommended 0.173 * Measured at 10% of rated current and 25C ambient temperature.
