The Bourns SF-0603S300-2 is a slow blow thin film chip fuse from the SinglFuse SF-0603S series, designed for overcurrent protection in space-constrained applications. It is rated for 3 A continuous current at 32 VDC and offers a breaking capacity of 50 A at both 35 VAC and 32 VDC.
This fuse features a typical resistance of 0.016 Ω (measured at 25 °C with ≤10% rated current, tolerance ±25%) and a melting I²t of 0.21 A²s (calculated at 10× rated current). The slow blow response time allows it to tolerate brief inrush currents without nuisance opening.
The component is housed in a miniature 0603 (1608 metric) surface mount package measuring 1.60 mm × 0.80 mm × 0.45 mm, suitable for automated assembly. It is RoHS3 compliant and halogen free, and carries UL (cUL) recognition under file E198545.
