0603SFS400F/32-2 Description

Short technical summary and product information.

The Littelfuse 0603SFS400F/32-2 is a surface mount slow-blow chip fuse designed for overcurrent protection in circuits that experience frequent current surges. Rated at 4A with a voltage rating of 32VDC, it offers a breaking capacity of 50A. The fuse has a cold DCR of 0.017Ω and a melting I²t of 2.3 A²s.

 

Its monolithic multilayer design provides strong arc suppression and high-temperature performance across an operating temperature range of -55°C to +125°C. The 0603SFS series is offered in the industry standard 0603 footprint (1.60mm x 0.80mm x 0.80mm), making it suitable for compact electronic assemblies.

 

The fuse is UL approved, RoHS compliant, halogen free, and ELV compliant. Typical applications include small motor systems, portable electronics, input power ports, power over Ethernet, test equipment, and POL converter protection.
