Bourns has announced the introduction of a new family of high inrush current withstanding thin-film SinglFuse™ SMD Fuses in an 0603 footprint to complement its already successful line of SinglFuse™ SMD Fuse products.

SF-0603HIxxxF Series of single blow fuses are designed for overcurrent protection. They have a high inrush current rating. These thin-film chip fuses are delivered in a surface-mount package suited for automated assembly. They are UL 248-14 listed.

These fuses are available in two voltage ratings, 35Vdc and 65Vdc. Current ratings for the 35Vdc fuses include 2A, 2.5A, 3A, 3.5A and 4A. Current ratings for the 65A fuses include 0.5A, 0.75A, 1A and 1.5A. Fusing time is within 60 seconds at 200% of rated current.

Bourns continues to broaden its portfolio of SinglFuse™ SMD Fuses to address the growing need for effective circuit protection in a variety of applications including PCs and monitors, server farms, portable memory, cell phones and tablets, digital cameras, gaming systems, set-top boxes, drones and robotics, white goods, battery chargers, and industrial controllers.
