The 118.1µin (3.00µm) tin thickness on both ends is standard for moderate-cycle applications — expect around 50 mating cycles before contact resistance starts climbing. The 3-wall shrouding and detent lock keep the mated pair aligned under vibration without needing a separate locking clip. Operating range is -40°C to 80°C — fine for indoor commercial and light industrial gear, but the 80°C ceiling means it stays out of high-ambient enclosures or engine compartments.
The 0.100" pitch sets the PCB hole pattern and routing density. Each contact carries 3A at 40V max — that's the per-contact ceiling before the temperature rise hits the housing limit. For a 12-position header, the total current budget is 36A if all contacts are loaded at once, but derate if ambient exceeds 25°C. Contact length - mating is 0.260" (6.60mm), overall contact length 0.563" (14.30mm), and the post length is 0.138" (3.50mm). The square male pin profile mates with standard AMPMODU Mod II receptacle contacts.
