The 1.25mm pitch and 0.049\" row spacing set the board footprint — at this density, the 0.5A per-contact current rating is consistent with signal-level duty, not power transmission. ## Surface Mount Termination and Board Guide Termination is solder, surface mount. The insulation material is Polyphenylene Sulfide (PPS), which handles the reflow profile without deformation — PPS has a high melting point and low moisture absorption, suited for lead-free soldering. The header is supplied in a tube.","metaTitle":"7-175643-2 TE Connectivity AMP Connectors Fine Pitch Header","metaDescription":"7-175643-2 TE Connectivity AMP Connectors Fine Pitch header, 12 positions, 2 rows, 1.25mm pitch, surface mount, shrouded, active production.
