It terminates through-hole with solder tails, making it a direct-fit choice for board-to-board signal or low-power interconnects where a shrouded housing isn't required. The tin-plated mating surface (100 µ\" thick) and phosphor bronze contacts are rated for 5 A per circuit at 110 V, with a UL94 V-0 black insulation body. ## What the ratings mean for the fit The 0.100\" pitch is the industry-standard grid for legacy and general-purpose PCB layouts — it routes easily on two-layer boards and leaves enough room for trace escape between pads. The 5 A per-circuit rating is typical for a tin-plated contact at this pitch; the limiting factor is the temperature rise of the unshrouded housing, not the contact itself. The 100 µ\" tin plating on the mating surface is a heavy deposition that withstands repeated insertion cycles better than a flash coat, though it will not match the cycle life of a gold-plated contact in a corrosive environment. ## Sourcing and lifecycle The 68657-403HLF carries an Active lifecycle status from Amphenol FCI — no end-of-life notice on record.","metaTitle":"Amphenol FCI 68657-403HLF BERGSTIK II Header, 3 Pos","metaDescription":"Amphenol FCI BERGSTIK II 68657-403HLF unshrouded pin header, 3 positions, 0.100\" pitch, 5 A, 110 V, tin-plated, UL94 V-0.
