SURFACEMOUNTFUSES
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.
