It carries a full population of square male pins on a 0.100" (2.54mm) pitch with an identical 0.100" row spacing, giving a dense but routable grid for signal-level interconnects. Rated at 5A per contact with a 110V voltage ceiling, it suits internal board-to-board wiring where the current draw per line stays under the 5A limit and the board stack-up accommodates the 0.730" (18.54mm) overall contact length. The phosphor bronze base alloy provides adequate spring retention for the push-pull fastening. The through-hole termination with a 0.200" (5.08mm) post length gives a solid mechanical anchor through the board, and the UL94 V-0 rated black insulation suits equipment installed inside an enclosure requiring a flame-rated component.
This 36-position dual-row header sits at the higher end of the BERGSTIK® II position count range. At the same 0.100" pitch and with the same tin-plated contacts, a 10-position sibling (79821-410HLF) serves low-circuit-count signal runs, while this 36-position version fills a board edge or mezzanine position that needs more I/O lines without moving to a denser pitch. The decision between them is strictly circuit count — the footprint pattern scales linearly, and the electrical ratings are identical across the family.
The push-pull retention means the mating connector's own friction and latch (if present) hold the pair together — there is no header-side locking feature. The through-hole solder tails are designed for wave or hand-solder assembly — no press-fit option on this order code.
