The contacts are phosphor bronze with 15.0 µ\" (0.38 µm) gold or GXT™ plating on the mating surface, rated 5 A per circuit. The unshrouded design gives the board layout engineer direct access to the pins for probing or wire-wrapping, but provides no polarization keying — the mating connector must be oriented correctly by the PCB footprint. The 0.100\" pitch is the de facto standard for 2.54 mm grid prototyping and production boards — any board laid out for a 0.100\" header accepts this part without a footprint change.","metaTitle":"78511-209HLF Amphenol BERGSTIK II Header, 9 pos","metaDescription":"78511-209HLF Amphenol BERGSTIK II single-row unshrouded male pin header, 9 circuits, 0.100\" pitch, through-hole, gold plating, 5 A, -65°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"78511-209HLF","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":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"78511","Number of Positions":"9","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"5A","Operating Temperature":"-65°C~125°C","Overall Contact Length":"0.538\\\" (13.67mm)","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4209","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/78511-209HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 78511-209HLF?","answer":"The header is rated 5 A per circuit.
