That thick tin finish handles repeated mating cycles in moderate environments — think test equipment, industrial control panels, or internal board stacking where gold is overkill and the budget matters. The insulation height is a low 0.100\" (2.54 mm), which keeps the profile tight above the PCB. The 0.100\" (2.54 mm) pitch is the defining dimension for board layout — it matches the vast majority of BergStik and legacy.025\" square-post receptacles. The through-hole termination uses a 0.120\" (3.05 mm) post length, which suits standard 0.062\" PCBs.","metaTitle":"Amphenol 79425-428HLF BergStik II Header, 28 Pos","metaDescription":"79425-428HLF BergStik II unshrouded header, 28 positions, 0.100\" pitch, 5 A, tin finish.
