The through-hole termination and 0.430\" (10.92mm) mating pin length give it a solid mechanical anchor in the PCB, while the 0.200\" (5.08mm) post length suits standard board thicknesses. The 0.100\" (2.54mm) pitch is the defining dimension for board layout — every via and trace route must align to that grid. The 30.0µin (0.76µm) gold or GXT™ plating on the mating surface is the contact finish that governs cycle life: at this thickness, the header can handle repeated mating and unmating without the contact resistance drift you'd see with tin plating in a low-insertion-force application.","metaTitle":"FCI BERGSTIK II 79821-136HLF Header, 36 Pos, 2.54mm","metaDescription":"FCI BERGSTIK® II header, 36 positions, 2 rows, 0.100\" pitch, unshrouded, through-hole, gold plating.
