It is a single-row, through-hole solder part with all positions loaded, making it a straightforward fit for any PCB layout that calls for a basic breakaway-style header. The tin-plated phosphor bronze contacts are rated 5 A per circuit, which is the typical signal-level current for this class of connector — adequate for logic-level power and I/O lines, but not intended for high-current bus distribution. ## Key specs and what they mean for the build The 0.100\" pitch matches the industry-standard grid, so the footprint is compatible with a wide range of mating receptacles and prototyping boards. The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for occasional mating cycles in a permanent or semi-permanent installation — think cable-to-board harnesses that get mated once at the factory and rarely disconnected in the field. Tin is a cost-effective choice for static assemblies; if the application requires frequent reconnection or operates in a corrosive environment, a gold-plated sibling in the same series would be the better call. The through-hole solder termination gives a mechanically robust joint that survives thermal cycling and vibration better than a surface-mount part of the same size. The 0.120\" (3.05 mm) post length is a standard dimension for soldering into a typical 1.6 mm thick PCB. The UL94 V-0 rated black housing means the connector meets the flammability requirement for equipment installed inside an enclosure — no special handling needed for compliance. Operating temperature range of -65°C to 125°C covers automotive under-hood, industrial cabinet, and outdoor telecom environments. The wide span means the connector's mechanical and electrical performance is stable across the full range — no derating needed unless the board itself has thermal limits.","metaTitle":"FCI 78511-410HLF BERGSTIK II Header, 10 Pos, 0.100\" Pitch","metaDescription":"FCI 78511-410HLF BERGSTIK® II unshrouded pin header, 10 positions, 0.100\" pitch, through-hole, tin-plated contacts rated 5 A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK® II","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"78511","Insulation Material":"-","Number of Positions":"10","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.538\\\" (13.67mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.318\\\" (8.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4872","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/78511-410HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 78511-410HLF?","answer":"The pitch is 0.100\" (2.54 mm), the standard industry grid for this class of pin header."},{"question":"Is the 78511-410HLF shrouded or unshrouded?","answer":"It is unshrouded — a bare pin header with no plastic shroud around the pins.
