PHYSICALSPECIFICATIONS:

Materials: Solder-Coated Copper Leads. R

Solderability: MIL-STD-202, Method 208.

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 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

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.
