The Amphenol 10119110-516002LF is the 16-circuit member of the BERGSTIK II unshrouded header series — a dual-row 0.100 inch (2.54 mm) pitch board-to-board header with right-angle through-hole termination. All 16 positions are loaded with square male pins. The mating face carries 30.0 µin (0.76 µm) gold plating over copper alloy, and the push-pull fastening type holds the mated pair without jack screws or tools — a feature that makes this series common in benchtop instrumentation and proto boards where frequent mating is routine. The housing is UL94 V-0 black, with an insulation height of 0.240 inch (6.10 mm).
Gold flash rating and what it means for duty
The 30.0 µin (0.76 µm) gold thickness on the mating face handles repeated mating cycles better than tin plating but is not rated for the multi-thousand-cycle service life that a thicker hard gold grade would provide. For production test fixtures or programmable bench use, the gold thickness is appropriate; for permanent board-to-board connections with no field service requirement, a tin-plated equivalent in the same series costs less with no functional penalty.
