Through-hole solder termination keeps the mechanical pull strength high; the 0.225\" (5.72 mm) post length gives enough tail for a standard 0.062\" board with room for a through-hole wave-solder fillet. Rated 5 A per circuit at 110 V, with tin-on-tin contacts — 100 µ\" (2.54 µm) tin on the mating side, tin on the post. Tin is a work-hardening finish: it wipes oxide on first mate but wears through after roughly 50–100 cycles. This header is built for a one-and-done or infrequent-mate board-to-board connection, not a daily-disconnect harness. The 31-position count is an oddball — not a standard 30 or 32 — so confirm the BOM line position count before committing the footprint.","metaTitle":"Amphenol BERGSTIK II 91276-431HLF Header, 31 Pos","metaDescription":"91276-431HLF BERGSTIK II single-row header, 31 positions, 0.100\" pitch, through-hole, tin-plated, 5 A, 110 V, UL94 V-0.
