The 0.100\" insulation height and 0.430\" mating pin length give a typical mated stack height around 0.530\" when paired with a standard receptacle. UL94 V-0 rated black housing. ## Pitch and row configuration Dual rows on a 0.100\" (2.54 mm) pitch, with a 0.100\" row spacing — the standard 0.100\" x 0.100\" grid. All 52 positions are loaded, so the footprint is a 2 x 26 array of 0.025\" square pins. The 0.200\" solder-tail length suits standard 0.062\" PCBs.","metaTitle":"79821-452HLF BERGSTIK II Header, 52 Pos, 0.100\" Pitch, 5 A","metaDescription":"FCI BERGSTIK II unshrouded header, 52 circuits, dual-row 0.100\" pitch, through-hole, tin-plated contacts rated 5 A.
