It uses the standard 0.100\" (2.54 mm) pitch on both rows and between rows, making it a direct fit for the classic 0.100-inch grid board layout. Rated for 5 A per contact with a 110 V voltage rating, this header is suited for signal-level board-to-board interconnects where a high pin count is needed in a compact, unshrouded footprint. The 30.0 µ\" gold plating on the mating surface gives it the mating cycle life for repeated board stack-ups or field service without contact fretting. ## What the Key Ratings Mean for Your Build The 52 positions are fully loaded across two rows, so every pin on the 26-pin-per-row pattern is present. The 0.100\" pitch is the de facto standard for prototyping and legacy bus architectures — your board footprint matches a wide ecosystem of BergStik receptacles and IDC connectors. The 30.0 µ\" gold finish is a solid industrial grade: it handles hundreds of mating cycles without exposing the phosphor bronze base metal, which matters if this header lives in a test fixture or a field-swappable card cage. The 5 A per contact rating is typical for signal paths; if you need to carry power through this header, derate for temperature rise and consider running multiple pins in parallel per the manufacturer's guidelines. ## Mating and Termination Fit This is an unshrouded male pin header with a push-pull fastening type. It mates with any standard 0.100\" pitch dual-row socket strip or IDC receptacle that accepts 0.025\" square posts. The 0.820\" (20.83 mm) mating pin length gives plenty of reach for stacking with standard receptacles. Termination is through-hole solder — the 0.120\" (3.05 mm) post length suits standard PCB thicknesses around 0.062\". The overall contact length of 1.040\" (26.42 mm) sets the board-to-board stack height when mated; verify the receptacle's insulation height against your z-height budget.","metaTitle":"87901-152HLF BergStik II Header, 52-Pos, 0.100\" Pitch, 5 A","metaDescription":"Amphenol ICC FCI BergStik II unshrouded header, 52 positions, 0.100\" pitch, 5 A, 30.0 µ\" gold.
