All 40 positions are loaded, making it a direct BOM match for a 40-circuit signal or low-power interconnect. ## What the Ratings Mean Rated 5 A per circuit at 110 V — the current is per-pin, not a total across the header, so a fully populated 40-pin connector can carry 5 A on each circuit as long as the aggregate temperature rise stays within the housing limits. The 30.0 µ\" (0.76 µm) gold plating on the mating surface is a mid-grade thickness: enough for hundreds of mating cycles in a clean environment, and the gold-on-gold interface avoids the fretting corrosion you get with tin-to-tin contacts in low-voltage signal paths. The UL94 V-0 rating means the black thermoplastic housing will self-extinguish within 10 seconds if ignited — a standard requirement for equipment inside an enclosure.","metaTitle":"Amphenol BERGSTIK II 86840-140HLF, 40-pos Header","metaDescription":"Amphenol BERGSTIK II 86840-140HLF 40-position dual-row header, 0.100\" (2.54mm) pitch, right-angle through-hole, gold 30µ\" contacts, rated 5A at 110V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"86840-140HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","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":"0.190\\\" (4.83mm)","Base Product Number":"86840","Number of Positions":"40","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.230\\\" (5.84mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.318\\\" (8.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f07eb009696ffe298bd4359a478f2e44.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/86840-140HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of the 86840-140HLF?","answer":"Rated 5 A per circuit at 110 V — the per-contact current is the limiting spec, not a total across the header."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/86840-140HLF","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/86840-140HLF when reusing this data.
