Rated for 600 V and -40°C to 105°C operation, with a UL94 V-0 liquid crystal polymer housing, this header suits applications in automotive, general-purpose industrial, medical, and telecommunications equipment where flame rating and a wide temperature range are required. The board lock is not optional for this SMT header — without it, the shear force from a cable tug during assembly can lift the solder joints. The locking ramp adds a second retention layer: the receptacle latch clicks over the ramp and holds the pair mated under vibration to the connector's rated temperature range.","metaTitle":"Molex 0430451217 Micro-Fit 3.0 Header, 12 Pos, 3.00mm, 8A","metaDescription":"Molex 0430451217 Micro-Fit 3.0 SMT header, 12 circuits, 3.00mm pitch, 8A per circuit, gold-plated contacts, board lock, 600V, 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 Cable/Wire","title":"0430451217","Series":"Micro-Fit 3.0 43045","Features":"Board Lock","Packaging":"Tape & Reel (TR)","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","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","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":"$3.6040","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0d721345d2d6d65d6196bb048814a0ce.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430451217/alternatives.json"},"ai":{"faq":[{"question":"Is 0430451217 shrouded?","answer":"Yes, it is a shrouded 4-wall header.
