The 0.016\" (0.40mm) pitch packs 40 circuits into a dual-row layout, with a low 0.045\" (1.14mm) height above the board. Gold flash contacts handle the signal duty in dense, space-constrained stacks — think handheld devices, portable instruments, or any assembly where the board gap is under 4mm. ## Stack Height Flexibility — Six Mated Gaps This header mates with the corresponding BergStak 0.40mm receptacle to produce one of six stacking heights: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm. The receptacle height determines the final gap — pick the receptacle part that gives you the board-to-board clearance your enclosure needs. At 1.5mm you're in ultra-slim territory; at 4mm there's room for passives on the underside.","metaTitle":"Amphenol FCI BergStak 0.40mm 10164228-0401A1RLF","metaDescription":"Amphenol FCI BergStak 0.40mm header, 40 positions, 0.40mm pitch, 1.14mm board height.
