Termination and board fit
The 0022288122 is the 12-position member of Molex's KK254 breakaway header line, terminated by through-hole solder with right-angle orientation. Gold-plated mating contacts on a 0.100" (2.54mm) pitch suit moderate-cycle signal applications; the unshrouded push-pull design mates with matching KK254 crimp housings.
Material and flammability rating
The glass-filled nylon (PA) housing carries a UL94 V-0 flammability rating, meeting the enclosure-level requirement for equipment inside a cabinet. Applications listed include automotive, general purpose, medical, and telecommunications — the V-0 rating supports use in equipment requiring flame-retardant components.
