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.
