Lead Pull Force: MIL-STD-202, Method 211, Test Condition A (will withstand a 5 lb. axial pull test). VARIATIONS IN DESIGN: Picofuses which differ from the standard 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 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 circuits.
