Dual-row 0.100\" (2.54 mm) pitch, tin-plated phosphor bronze contacts rated 3 A per contact, surface-mount termination, UL94 V-0 thermoplastic housing, -65°C to 125°C operating range. ## Row spacing and breakaway flexibility Row-to-row spacing is 0.100\" (2.54 mm), matching the mating pitch — the 34-position header mates with a 34-position receptacle on the same 2.54 mm grid. The breakaway design allows depopulating the pin strip to a shorter length if the board layout requires fewer than 34 circuits.","metaTitle":"Amphenol BERGSTIK 95278-402B34LF Header, 34-Pos 2.54mm","metaDescription":"Amphenol FCI BERGSTIK 95278-402B34LF: 34 positions, dual row, 0.100\" (2.54 mm) pitch, tin-plated contacts, 3 A per contact, SMT, UL94 V-0.
