SF-1206S125-2 is a slow blow thin film chip fuse designed for overcurrent protection in compact surface mount applications. It features a 1.25 A rated current with a typical resistance of 90 mO and an I²t rating of 0.155 A²s, providing reliable protection with a 50 A breaking capacity. The fuse is housed in a miniature 3216 (EIA 1206) footprint and is UL listed (UL 248-14), RoHS compliant, and halogen free, making it suitable for automated assembly and lead-free soldering processes. Operating over a temperature range of -20°C to +105°C, this fuse is ideal for portable memory devices, LCD monitors, disk drives, battery chargers, and industrial controllers where space constraints and reliable overcurrent protection are essential.
