VARIATIONS IN DESIGN: Picofuses which differ from the stan-
dard versions as presented on this page can be provided for a
commercial or military use. One such design version is where
the picofuse terminates at one end of a pin for use as a single or
1
multi-pin connector. Extreme accuracy in blowing time at 300% or
more of rating, makes these picofuses suitable for use in circuits
where sequential switching or redundancy may be required. The
small size of the fuse, its non-hygroscopic characteristic and
infinitesimal weight makes it the ideal fuse for micro-electronic
0.1
circuits.
