• For new designs of 7 amp please consult 429 series.  
• The SlimLine 1206 fuse is an extremely small, low profile design  
(1206 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 application.  
• Mounting pad and electrical specification are identical to the popular  
429 Series specifications.
