Surface Mount Fuses  
Thin-Film Surface Mount  
SlimLine™ 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.
