SF-1206S300-2 is a slow blow thin film surface mount fuse designed for overcurrent protection in compact electronic applications. It features a 3.0 A rated current with a typical resistance of 23 mO and an I²t value of 0.933 A²s, providing reliable protection against transient overcurrent events. The fuse is housed in a miniature 3216 (EIA 1206) footprint with surface mount packaging for automated assembly, and is UL listed (UL 248-14), RoHS compliant, and halogen free. It operates over a temperature range of -20°C to +105°C and exhibits a fusing time within 5 seconds at 250% of rated current. This fuse is commonly used in portable memory devices, LCD monitors, disk drives, digital cameras, cell phones, rechargeable battery packs, and industrial controllers where space constraints and reliable overcurrent protection are essential.
