SURFACE MOUNT FUSES THIN-FILM SURFACE MOUNT Slim 1206 Very Fast-Acting Thin-Film Type 433 Series ® ® • The Slim 1206 is an extremely small, low profile design (1206 chip size) utilizing thin-film technology to achieve precise control of electrical characteristics. • One-piece element/termination design assures extra reliability by eliminating the need for soldering, welding or other joining operations in the manufacture of the fuse. • 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.
