SURFACE MOUNT FUSES
THIN-FILM SURFACE MOUNT
SlimLine 0603
Very Fast-Acting Thin-Film Type 434 Series
鈥?The SlimLine 0603 is an extremely small, low profile
design (0603 chip size) utilizing thin-film technology to
achieve precise control of electrical characteristics.
鈥?The lower height profile produces a flat surface for
improved performance in pick-and-place operations and
an alternate solution for height critical applications.
鈥?Mounting pad and electrical specifiation are identical to
the popular 431 Series specifications.
