Bourns SF-2923HC-C SinglFuse™ SMD Fuses

Bourns SF-2923HC-C SinglFuse™ SMD Fuses are designed with high-current ceramic housing for overcurrent protection. These fuses utilize a robust ceramic cube housing, silicone insulation, and a single fuse-termination element. This enables the products to withstand higher inrush current with higher reliability in harsh environments and more effective fusing action when opening. Bourns SF-2923HC-C SinglFuse SMD fuses are UL 248-14 listed and are intended for use in a variety of power applications. Typical applications include lithium-ion battery packs, power tools, Power Factor Correction (PFC), Energy Storage Systems (ESS), and electric assist bicycles.
