| Surface Mount Fuses Thin-Film Surface Mount SlimLineTM 0603 Very Fast-Acting Fuse 434 Series * For RoHS compliant and Lead-Free designs use 467 series. * The SlimLine 0603 fuse is an extremely small, low profile design (0603 chip size) utilizing thin-film technology to achieve precise control of electrical characteristics. * The lower height profile produces a flat surface for improved performance in pick-and-place operations and an alternate solution for height critical applications.
