The 0.118\" (3.00mm) solder post length suits standard through-hole PCB thicknesses (1.6mm typical) with enough tail for a reliable solder fillet on the bottom side.","metaTitle":"71991-302HLF Dubox 4-Pin Female Socket Header, 0.100\" Pitch","metaDescription":"71991-302HLF Amphenol ICC (FCI) Dubox 4-position dual-row receptacle, 0.100\" pitch, 30.0µin gold mating finish, 11.04mm stack height.
