SF-0603S500-2 is a slow blow thin film chip fuse designed for overcurrent protection in compact surface mount applications. It features a 5.0 A rated current with a typical resistance of 8 mO and an I²t value of 0.622 A²s, providing reliable protection with minimal voltage drop. The fuse operates at a rated voltage of DC 50 V with a breaking capacity of 50 A, and is housed in a miniature 1608 (EIA 0603) footprint suitable for automated assembly. It meets UL 248-14 standards, is RoHS compliant, and halogen free, with an operating temperature range of -20°C to +105°C. Common applications include portable memory devices, LCD monitors, disk drives, cell phones, rechargeable battery packs, and industrial controllers where space constraints and reliable overcurrent protection are essential.
