Rated 5 A per circuit at 110 V, this header handles signal duty comfortably and can carry moderate power within a board stack — the 5 A per contact is typical for the BergStik platform and is limited by the temperature rise of the UL94 V-0 housing material. The through-hole solder tails are 0.200\" (5.08 mm) long, and the overall contact length is 0.730\" (18.54 mm), which sets the mated stack height when paired with a standard receptacle. The 46 positions are fully loaded across two rows at a 0.100\" (2.54 mm) row spacing.","metaTitle":"Amphenol BERGSTIK II 79821-146HLF, 46-pos 0.100\" Header, 5A","metaDescription":"Amphenol BERGSTIK II 79821-146HLF dual-row unshrouded header, 46 positions, 0.100\" pitch, 5 A, 110 V, through-hole, gold 30 µ\".","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-146HLF","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":"46","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":"$4.4235","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-146HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of the 79821-146HLF?","answer":"The 79821-146HLF is rated 5 A per circuit at 110 V, which is typical for the BergStik II platform and sufficient for signal and light power distribution."},{"question":"What is the gold plating thickness on the 79821-146HLF?","answer":"The contact finish on the mating surface is 30.0 µ\" (0.76 µm) gold, a high-durability plating that supports repeated mating cycles."},{"question":"Does the 79821-146HLF have a locking feature?","answer":"No, this is an unshrouded header with a push-pull fastening type — no locking latch or polarization key."},{"question":"What is the mating connector for the 79821-146HLF?","answer":"The 79821-146HLF mates with standard 0.100\" (2.54 mm) pitch female receptacles, such as BergStik II socket strips or IDC ribbon cable connectors with the same pitch and row spacing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/79821-146HLF","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/79821-146HLF when reusing this data.
