The 3.00 mm pitch and 0.118\" row spacing give enough creepage for the 600 V rating without forcing an oversized board footprint. Termination is through-hole with a kinked pin — the bend locks the pin in the plated hole during solder wave, preventing float and ensuring the 0.125\" post length sits correctly for the board thickness and solder fillet.","metaTitle":"Molex Micro-Fit 3.0 430451812, 18-Position Header, 8A","metaDescription":"Molex 430451812 Micro-Fit 3.0 header, 18 circuits dual-row, 3.00mm pitch, 8A per circuit, 600V, shrouded 4-wall, locking ramp, through-hole, tin contacts, UL94","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":"430451812","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 18POS 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":"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":"$3.74","priceTiers":[{"qty":1,"price":"$3.74000","currency":"USD"},{"qty":10,"price":"$3.29200","currency":"USD"},{"qty":80,"price":"$2.61838","currency":"USD"},{"qty":1440,"price":"$2.16951","currency":"USD"},{"qty":5040,"price":"$1.94508","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/caadff08674a6744feb617fafa9e5d8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451812/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of molex 430451812?","answer":"The mating pitch is 3.00 mm (0.118\") with the same 0.118\" row spacing — a standard dual-row footprint that matches the Micro-Fit 3.0 receptacle family."},{"question":"Is molex 430451812 rohs compliant?","answer":"Yes, it is listed as ROHS3 Compliant, covering the full EU RoHS exemption set."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430451812","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/430451812 when reusing this data.
