It carries 44 positions loaded all, with a 0.100\" row spacing that matches legacy 0.100\" grid layouts. Rated 5 A per contact at 110 V, with 30 µ\" (0.76 µm) gold or Gold, GXT™ plating on the mating surface over phosphor bronze contacts, it suits signal and moderate-power distribution in industrial control, test equipment, and telecom backplanes. The 0.100\" pitch and row spacing mean this header drops onto a standard 0.100\" grid PCB — no custom footprint needed, and it mates with any 0.100\" pitch female receptacle or IDC socket. The overall contact length of 0.730\" (18.54 mm) gives a 0.430\" (10.92 mm) mating interface and a 0.100\" (2.54 mm) insulator height above the board.","metaTitle":"Amphenol FCI 79821-144HLF BERGSTIK II Header, 44 Pos","metaDescription":"Amphenol FCI BERGSTIK II 79821-144HLF, 44-position dual-row male header, 0.100\" pitch, 5 A, 30 µ\" gold, through-hole, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-144HLF","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":"79821","Number of Positions":"44","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.730\\\" (18.54mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.430\\\" (10.92mm)","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":"$4.9526","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-144HLF/alternatives.json"},"ai":{"faq":[{"question":"Is the 79821-144HLF available via RFQ confirmation?","answer":"Contact the storefront with your BOM for a same-day quote."},{"question":"What is the price for 79821-144HLF?","answer":"Pricing is confirmed at quote time based on quantity and current market conditions.
