The 30.0 µin gold or GXT plating on the mating surface gives it the cycle life and corrosion resistance for repeated matings in controlled environments, while the UL94 V-0 rated black housing meets the flammability requirements for equipment inside an enclosure. The 5 A per contact rating is typical for a 0.100-inch pitch header — the limiting factor is the temperature rise in the housing at full load across all 56 positions, so derate the per-contact current if the assembly runs warm. The 110 V voltage rating reflects the creepage distance available on the unshrouded header, adequate for signal-level and low-voltage power interconnects within a board stack. The 0.770-inch (19.56 mm) mating contact length gives substantial wipe before full engagement, ensuring reliable contact even with some board-to-board misalignment. The 0.120-inch (3.05 mm) solder post length suits standard through-hole PCB thicknesses — the post protrudes enough for a solid solder fillet without excessive tail length. ## Unshrouded Header — Placement and Polarization The 0.100-inch insulation height keeps the pin tips low-profile, which helps in tight board stacks.","metaTitle":"87052-156HLF BergStik II Header, 56-Pos, 0.100\" Pitch","metaDescription":"FCI/Berg 87052-156HLF BergStik II unshrouded header, 56 positions, dual-row 0.100\" pitch, 5 A, 30 µ\" gold plating.
