Rated 250V, with current depending on the wire gauge of the crimp terminal used in the mating half. ## Board-fit details for layout The 0.364\" (9.25 mm) insulation height gives clearance for components under the overhang; row spacing is also 3.00 mm, so the footprint is a 3.00 mm square grid.","metaTitle":"4-794638-2 TE Connectivity Micro MATE-N-LOK Header SMD","metaDescription":"4-794638-2 TE Connectivity AMP Connectors Micro MATE-N-LOK header, SMD, 12 positions, 3.00 mm pitch, gold mating finish, active production.
