It is a single-row, through-hole solder part with tin-plated phosphor bronze contacts — rated 5 A per circuit at 110 V. The black UL94 V-0 housing carries a 0.100 inch insulation height, and the full pin length measures 1.225 inches from the seating plane to the tip, with a 0.900 inch mating section and a 0.225 inch solder post. ## What the ratings mean for the fit The 0.100 inch pitch is the standard legacy footprint — it matches the vast installed base of 0.100 inch header strips and IDC sockets, so board layout is straightforward if you are working with existing tooling or a known BOM. The 5 A per circuit rating is typical for a tin-plated signal header at this pitch; the limiting factor is the contact temperature rise in still air, not the contact material itself. Tin plating on both the mating surface and the post (100.0 µin on the mating side) keeps the cost down for applications that do not need the cycle life of gold — expect a few dozen mating cycles before the tin wears, which is fine for one-time board assembly or periodic service but not for frequent field disconnect. ## Board layout and termination Through-hole solder termination with a 0.225 inch post length. The unshrouded design gives direct access to the pins for probing or manual wiring.","metaTitle":"Amphenol FCI 91276-412HLF BERGSTIK II Header, 12 Pos","metaDescription":"91276-412HLF unshrouded male header, 12 positions, 0.100\" pitch, 5 A, 110 V.
