• 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 perform-
ance 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.
