It uses a standard 0.100\" (2.54mm) pitch on both positions and rows, matching the footprint of legacy and current BergStik receptacles. The through-hole solder termination and push-pull fastening make it a straightforward fit for a PCB that needs a male pin interface for a mating female socket. ## What the Ratings Mean for the Fit Rated 5 A per contact at 110 V, this header handles signal-level currents and moderate power distribution across the 16 circuits. The 30.0 µin gold or GXT™ plating on the mating surface supports repeated mating cycles without oxidation, while the phosphor bronze contact material provides consistent spring force over the life of the connection. The 0.100\" pitch and row spacing are the de facto standard for BergStik-compatible layouts, so the board footprint is well-defined. ## Board Layout and Mating Considerations The unshrouded design exposes the 0.430\" (10.92mm) mating pins, which mate with any standard 0.100\" pitch female socket header or IDC receptacle. The overall contact length of 0.730\" (18.54mm) includes a 0.200\" (5.08mm) solder tail for through-hole mounting. The insulation height of 0.100\" (2.54mm) keeps the header low-profile on the board. The UL94 V-0 rated black housing meets the flammability requirement for equipment inside an enclosure.","metaTitle":"79821-116HLF BergStik II Header, 16-Pos, 0.100\" Pitch, 5A","metaDescription":"FCI/Amphenol 79821-116HLF BergStik II unshrouded header, 16 positions, dual-row, 0.100\" pitch, 5A, gold plating.
