The Amphenol BERGSTIK® II 79821-110HLF is a 10-position, dual-row unshrouded male header on a standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect, terminated through-hole with solder, and uses a push-pull fastening — no latch, straight in and out. The contacts are square pins, gold or Gold, GXT™ plated to 30.0 µin (0.76 µm) on the mating surface, rated for 5 A per contact at 110 V. The housing is black UL94 V-0 rated material.
This is the 10-position fully loaded member of the BERGSTIK® II family (base number 79821). The 0.100" (2.54 mm) pitch and row spacing match the standard legacy footprint, and the 0.430" (10.92 mm) mating pin length gives a solid wipe before the square pin seats in a receptacle. The overall contact length is 0.730" (18.54 mm), with a 0.200" (5.08 mm) post for the PCB through-hole.
The 0.100" (2.54 mm) pitch and row spacing (also 0.100") mean this header drops into the standard 0.100" x 0.100" grid footprint — no board layout surprises.
