The square pins are phosphor bronze with a gold or GXT™ mating finish at 15.0µin (0.38µm) minimum, giving it reliable contact resistance over repeated mating cycles in corrosive or field-service environments. Rated 5 A per contact with an operating temperature range of -65°C to 125°C, this header handles signal-level currents and low-power distribution in environments from cold storage to underhood automotive. ## Mating and board-fit details The 0.318\" (8.08mm) mating pin length engages with standard BERGSTIK II receptacle housings or IDC sockets on the same 0.100\" pitch. The 0.120\" (3.05mm) solder post length suits 1.6mm-thick PCBs with standard through-hole plating. The overall contact length of 0.538\" (13.67mm) includes both the mating pin and the solder tail — this dimension matters when calculating the standoff height between stacked boards.","metaTitle":"FCI 78511-204HLF BERGSTIK II Header, 4 Pos, 2.54mm","metaDescription":"FCI BERGSTIK® II unshrouded header, 4 positions, 0.100\" pitch, 5 A, gold/GXT plating, -65 to 125°C, UL 94 V-0.
