With a 0.100\" (2.54 mm) pitch and dual rows spaced at the same 0.100\", it matches the standard footprint used across legacy and current PCB layouts. The male square pins are through-hole soldered, and the push-pull fastening means no locking latch — the retention comes from the mating friction and the solder joints. Rated 5 A per contact at 110 V, this header is sized for signal-level power distribution and general-purpose I/O, not high-current bus bars. The 30.0 µ\" (0.76 µm) gold GXT™ plating on the mating surface is the key differentiator here — it supports repeated mating cycles and holds up in corrosive or humid environments where tin-plated contacts would degrade. The phosphor bronze base material adds spring retention over the life of the connection. ## Operating Range and Compliance The operating temperature spans -65°C to 130°C, covering industrial cabinet heat and cold-start conditions without derating the current at the low end. The thermoplastic housing carries a UL94 V-0 flammability rating, which meets the enclosure fire-safety requirement for equipment installed inside a panel or rack. The 0.100\" (2.54 mm) insulation height and 0.230\" (5.84 mm) mating contact length give a standard stack height when paired with a matching receptacle — the overall contact length of 0.425\" (10.80 mm) and post length of 0.095\" (2.41 mm) define the through-hole solder tail protrusion below the board.","metaTitle":"Amphenol 75844-648-26LF BergStik Header, 26 Pos","metaDescription":"26-position unshrouded breakaway header, 0.100\" pitch, 30.0 µ\" gold GXT plating, 5 A, 110 V.
