It uses the industry-standard 0.100\" (2.54mm) pitch on both the mating interface and between rows, making it a direct fit for standard perfboard or grid-based layouts. The header is through-hole soldered, with a 0.430\" (10.92mm) mating pin length and a 0.200\" (5.08mm) solder tail for through-board connection. Rated at 5 A per contact with a 110 V voltage rating, it handles moderate signal and low-power distribution duties. The UL94 V-0 rated black housing and tin-plated phosphor bronze contacts suit general-purpose internal wiring where repeated mating cycles are limited. ## Tin-plated contacts and what that means for your build The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for moderate-cycle applications — think a few dozen matings over the product life. Tin is a cost-effective choice for stable, low-vibration environments where the connector is not regularly disconnected. For high-cycle or corrosive environments, a gold-plated sibling in the same series would be the better call, but the tin finish here keeps the per-unit cost down for volume builds.","metaTitle":"FCI 79821-470HLF BERGSTIK II Header, 70 Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK II 79821-470HLF unshrouded header, 70 positions, 0.100\" pitch, 5 A, tin plating.
