The tin-plated contacts are rated 8 A per circuit at 600 V, with a UL94 V-0 liquid crystal polymer housing that handles -40°C to 105°C operating temperatures. Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, mid-current wire-to-board connection is needed. The 3.00 mm pitch is standard for the Micro-Fit 3.0 family, meaning the board footprint matches the receptacle side exactly — no layout surprises.","metaTitle":"Molex Micro-Fit 3.0 430451800, 18-Pin Header, 8 A, 600 V","metaDescription":"Molex 430451800 Micro-Fit 3.0 header, 18 positions dual-row, 3.00 mm pitch, right-angle through-hole, 8 A per circuit, 600 V, tin-plated, active production","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":"430451800","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER R/A 18POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, 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 Alloy","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","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.44","priceTiers":[{"qty":1,"price":"$5.44000","currency":"USD"},{"qty":10,"price":"$4.78400","currency":"USD"},{"qty":80,"price":"$3.80525","currency":"USD"},{"qty":1440,"price":"$3.15292","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/bd091ed87d91909cb3a616092ba2b455.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451800/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of Molex 430451800?","answer":"The pitch is 0.118\" (3.00 mm), which is standard for the Micro-Fit 3.0 family and matches the receptacle footprint exactly."},{"question":"What is the current rating for 430451800?","answer":"The current rating is 8 A per circuit at 600 V, though derating applies above 25°C ambient depending on the number of circuits powered and enclosure airflow."},{"question":"Is 430451800 RoHS compliant?","answer":"Yes, it is ROHS3 compliant, as listed in the lifecycle record."},{"question":"What is the mating connector for 430451800?","answer":"It mates with the matching Micro-Fit 3.0 receptacle housing (sold separately), which accepts 20-24 AWG wire with the appropriate crimp terminal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451800","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/430451800 when reusing this data.
