This is a through-hole solder-terminated board-to-board interconnect — the square pins are phosphor bronze with a gold or Gold GXT™ mating finish at 30.0µin (0.76µm) thickness, rated for 5 A per circuit at 110 V. The 0.100\" pitch and row spacing are the industry-standard grid — your board footprint is a 2x20 pattern of 0.025\" square holes on 0.100\" centers, which matches decades of legacy layout conventions. The through-hole solder tails are 0.200\" (5.08mm) long, suitable for standard 0.062\" to 0.093\" PCBs. The overall contact length of 0.730\" (18.54mm) gives you a 0.430\" (10.92mm) mating interface above the insulator.","metaTitle":"Amphenol FCI 79821-140HLF BERGSTIK II Header, 40 pos","metaDescription":"Amphenol FCI BERGSTIK II 40-position unshrouded header, 0.100\" pitch, dual-row, gold-plated contacts, 5 A, 110 V, through-hole, UL94 V-0.
