What This 30-Position SMT Socket Does
The 1-147105-5: The 2 A per-contact rating is conservative given the gold interface and phosphor bronze contact material — the current ceiling is bounded by the housing's temperature rise at 2 A, not the contact itself.
Surface-mount termination with a pick-and-place feature means this part is reflow-compatible and can be placed by automated assembly equipment. The 0.265" (6.73 mm) insulation height gives a moderate stack height for mezzanine or right-angle board-to-board connections — check your z-height budget against the mating header's mated height. The black glass-filled polyester housing (UL94 V-0 rated per typical AMPMODU material) provides flame resistance for equipment inside an enclosure.
