## Description
The Eaton Bussmann SS-5F-1A-AP is a 1 A, 250 VAC fast-acting subminiature PCB fuse engineered to UL 248-14 standards for primary and secondary overcurrent protection. Featuring a radial-leaded through-hole package measuring 8.7 mm x 4.5 mm with an 8.05 mm profile height, this component optimizes printed circuit board real estate in dense electronic assemblies. Built with a plastic cap and base exhibiting a UL 94V-0 flammability rating, the fuse delivers a robust 50 A AC breaking capacity at its rated voltage, a typical cold resistance of 165.5 mΩ, and a melting $I^2t$ of 2.22 $\text{A}^2\text{s}$.
This device is well-suited for integration into power supplies, notebook computers, white goods, lighting ballasts, power adapters, set-top boxes, and LED/LCD displays. Operating reliably across a wide temperature range of -40 °C to +125 °C (subject to thermal derating), the SS-5F series meets stringent environmental requirements as a halogen-free, lead-free, and RoHS-compliant circuit protection solution. It carries cULus recognition and PSE agency certifications, ensuring compliance for international commercial deployments. The -AP ordering code designates packaging in a 1000-part ammo pack with a 12.7 mm lead pitch, facilitating automated board assembly.
