It carries gold-plated mating contacts (15.0 µ\" gold over nickel) with tin-plated solder tails, and the shrouded 4-wall design with a locking ramp gives positive retention against the mating receptacle. This header is specified for automotive, general purpose, industrial, medical, and telecommunications applications — the -40°C to 105°C operating range and UL94 V-0 LCP housing suit it for environments inside enclosures that require flame-rated materials and temperature cycling. The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint — it's a common pitch for wire-to-board power interconnects in harness assemblies. The 8 A per circuit rating is the headline current at the contact level; the 15.0 µ\" gold on the mating side supports repeated mating cycles in field-service applications, while the tin on the solder tail keeps the board-level joint cost-effective.","metaTitle":"Molex Micro-Fit 3.0 430451807, 18-Position SMT Header, 8A","metaDescription":"Molex 430451807 Micro-Fit 3.0 header, 18 circuits, 3.00mm pitch, 8A per circuit, gold-plated contacts, SMT right-angle, board lock.","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":"430451807","Series":"Micro-Fit 3.0 43045","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER SMD R/A 18POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount, Right Angle","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":"0.290\\\" (7.37mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"18","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.13","priceTiers":[{"qty":1,"price":"$8.13000","currency":"USD"},{"qty":10,"price":"$7.07000","currency":"USD"},{"qty":100,"price":"$5.83280","currency":"USD"},{"qty":200,"price":"$5.83275","currency":"USD"},{"qty":1000,"price":"$4.84295","currency":"USD"},{"qty":2000,"price":"$4.70155","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451807/alternatives.json"},"ai":{"faq":[{"question":"Is 430451807 compatible with Micro-Fit 3.0 receptacles?","answer":"Yes, this header mates with the matching Micro-Fit 3.0 receptacle housings that accept the standard Micro-Fit 3.0 crimp terminals."},{"question":"Is 430451807 RoHS compliant?","answer":"Yes, the 430451807 is ROHS3 compliant per the manufacturer's listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451807","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/430451807 when reusing this data.
