SURFACE MOUNT FUSES

THIN-FILM SURFACE MOUNT

SlimLine 0603 Very Fast-Acting Thin-Film Type 434 Series

• The SlimLine 0603 is an extremely small, low profile

design (0603 chip size) utilizing thin-film technology to

achieve precise control of electrical characteristics.

• 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.
