It's a board-to-wire interconnect: the header solders into a PCB, and a matching receptacle housing with crimp terminals locks onto it. The 600 V voltage rating at this pitch gives good creepage for mains-isolated circuits without blowing up the board footprint. Contact plating is split: the mating side is gold at 15.0 µin (0.38 µm), the solder tail is tin at 100.0 µin (2.54 µm). The tin post is purely for solderability; the thick 100.0 µ\" tin wets well in wave or hand solder. The housing is black LCP (Liquid Crystal Polymer) glass-filled, rated UL94 V-0. ## Mating and Termination Reality The matching receptacle part numbers are in the 43025 series (crimp housings) or 43645 series (pre-loaded wire assemblies). For the crimp terminals, use Molex 43030 or 43031 series contacts, 20-24 AWG, with the correct hand tool or press. The through-hole post length is 0.125\" (3.18 mm) — standard for 1.6 mm PCBs; the insulation height of 0.390\" (9.91 mm) means the shroud sits well above the board, giving clearance for the receptacle body.","metaTitle":"Molex Micro-Fit 3.0 0430451028 Header, 10 Pos, 3mm, 8A","metaDescription":"Molex 0430451028 Micro-Fit 3.0 header, 10 circuits, 3.00mm pitch, 8A per circuit, 600V, gold mating contacts, shrouded, through-hole.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"0430451028","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9200","priceTiers":[{"qty":1,"price":"$2.92000","currency":"USD"},{"qty":10,"price":"$2.57000","currency":"USD"},{"qty":80,"price":"$2.04413","currency":"USD"},{"qty":1224,"price":"$1.69369","currency":"USD"},{"qty":2448,"price":"$1.57689","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/955975b21a3e7e0c1f6da7f32573f210.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430451028/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 0430451028?","answer":"The 0430451028 mates with a Micro-Fit 3.0 receptacle housing of the same circuit count — 10 positions, dual-row.
