It's built for board-to-wire power distribution in automotive, industrial, medical, and telecom gear, carrying 8 A per circuit at 600 V. The 30 µin gold on the mating surface handles repeated connect/disconnect cycles without fretting, and the 4-wall shrouding protects the square male pins during handling and guides the receptacle home. Mates with the matching Micro-Fit 3.0 receptacle housing (e.g. 43025 series) loaded with the appropriate crimp terminals. The locking ramp gives an audible click when fully seated — you'll feel it latch. On site, that ramp is what keeps the connection from backing out under vibration; if you're re-pinning a harness, the terminals are field-serviceable with the standard Molex hand tool. The 8 A per circuit rating at 600 V means this header carries real power — it's sized for the main DC rail or a motor feed, not a signal line. Derate above the ambient temperature the harness sees.","metaTitle":"Molex Micro-Fit 3.0 430451029, 10 Pos Header, 3mm, 8A","metaDescription":"Molex Micro-Fit 3.0 430451029 vertical header, 10 positions, 3.00mm pitch, 8A per circuit, 600V, gold contacts, locking ramp.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Style":"Board to Cable/Wire","title":"430451029","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 10POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.118\\\" (3.00mm)","Voltage Rating":"600V","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.390\\\" (9.91mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"10","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.06","priceTiers":[{"qty":1,"price":"$4.06000","currency":"USD"},{"qty":10,"price":"$3.57600","currency":"USD"},{"qty":80,"price":"$2.84475","currency":"USD"},{"qty":1224,"price":"$2.35712","currency":"USD"},{"qty":2448,"price":"$2.19455","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/955975b21a3e7e0c1f6da7f32573f210.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451029/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does the 430451029 carry?","answer":"The 430451029 is ROHS3 compliant and the housing carries a UL94 V-0 flammability rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451029","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/molex/430451029 when reusing this data.
