It carries 8 A per circuit at 600 V, with 30.0 µin gold on the mating contacts and 100.0 µin tin on the solder tails — a plating split that gives the mating interface corrosion resistance for repeated cycles while keeping the solder joint cost-effective. The 3.00 mm pitch and 0.118\" row spacing define the board footprint — a 12-position, 2-row layout that matches the standard Micro-Fit 3.0 receptacle. The 8 A per circuit rating is derated from the contact's thermal rise; at the 105 °C upper operating limit, expect to reduce current per the manufacturer's derating curve.","metaTitle":"Molex Micro-Fit 3.0 430451229, 12 Pos Header, 8A, 600V","metaDescription":"Molex Micro-Fit 3.0 430451229 header, 12 circuits, 3.00 mm pitch, 8 A per circuit, 600 V, gold mating contacts, through-hole, active production, sourced to","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":"430451229","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 12POS 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":"12","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","Operating Temperature":"-40°C ~ 105°C","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":"$4.78","priceTiers":[{"qty":1,"price":"$4.78000","currency":"USD"},{"qty":10,"price":"$4.21000","currency":"USD"},{"qty":80,"price":"$3.34900","currency":"USD"},{"qty":1008,"price":"$2.77493","currency":"USD"},{"qty":3024,"price":"$2.58356","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451229/alternatives.json"},"ai":{"faq":[{"question":"What is the mating part for 430451229?","answer":"The 430451229 mates with a Micro-Fit 3.0 receptacle housing that accepts the series' crimp terminals.
