SURFACE MOUNT FUSES THIN-FILM SURFACE MOUNT Slim 0603 Very Fast-Acting Thin-Film Type 434 Series • The Slim 0603 is an extremely small, low profile design (0603 chip size) utilizing thin-film technology to achieve precise control of electrical characteristics. • One-piece element/termination design assures 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 applications. • Mounting pad and electrical specifiation are identical to the popular (431) Series specifications.
