Tin-plated phosphor bronze contacts carry 5 A per circuit at 110 V, which is typical for signal-level duty on a board-to-board interconnect; the 100.0 µin (2.54 µm) tin plating on the mating surface handles a moderate number of mating cycles in a permanent or semi-permanent install. Through-hole solder termination with a 0.120\" (3.05 mm) post length — the solder tail sits comfortably in a standard 0.062\" board and leaves enough protrusion for a reliable fillet. The 0.100\" (2.54 mm) row spacing mirrors the pitch, so the 52 positions occupy a 2.6-inch row of holes on 0.100\" centers.","metaTitle":"Amphenol FCI BERGSTIK II 87052-452HLF, 52-pos 0.100\" Header","metaDescription":"Amphenol FCI BERGSTIK II 87052-452HLF, 52-position 0.100\" (2.54 mm) pitch dual-row male header, 5 A per circuit, tin-plated contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"87052-452HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"87052","Number of Positions":"52","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.990\\\" (25.15mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.770\\\" (19.56mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.4154","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/87052-452HLF/alternatives.json"},"ai":{"faq":[{"question":"What is 87052-452HLF's listed style on this component line?","answer":"The listed style is Board to Board, confirming it is a board-to-board header rather than a wire-to-board or panel-mount connector."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/87052-452HLF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/87052-452HLF when reusing this data.
