For a closer gold-plating match, the 1376779-2 also carries a 3 A rating and gold mating finish, but at 8 µinch thickness — a quarter of this part's 30 µinch. If you need the higher cycle life that 30 µinch gold provides, 9-146277-0-04 is the right call.","metaTitle":"9-146277-0-04 TE Connectivity AMP Connectors Header 4POS","metaDescription":"9-146277-0-04 TE Connectivity AMP Connectors AMPMODU Mod II header, 4 positions, 0.100\" (2.54mm) pitch, unshrouded, gold mating finish.
