The connector is surface-mount with integrated board guide, pick-and-place cap, and solder retention features, making it compatible with standard SMT reflow lines. ## Stacking Height and Board Fit The mated stacking height is 6mm, with the header itself standing 5.30mm above the board. The 0.50mm pitch drives a dense footprint: 144 circuits in two rows means the board layout needs careful routing, especially for differential pairs or high-speed signals. ## Comparing Stack Heights Within the FX10 Family The same-series sibling 10147520-144-SHLF shares the same 144-position count, 0.50mm pitch, and 30.0µin gold plating, but its height above board is 3.50mm instead of 5.30mm. That difference translates to a lower mated stack — roughly 4mm versus 6mm — which matters when the z-height budget in the enclosure is tight. Both are active and use the same footprint, so swapping between them is a board-layout decision, not a re-spin.","metaTitle":"Amphenol FCI 10147520-144-THLF Bergstak FX10 Header, 144 Pos","metaDescription":"Amphenol FCI Bergstak FX10 0.5mm header, 144 positions, 0.50mm pitch, 6mm stacking height, 30µin gold, RoHS.
