It is the board-side half of a board-to-cable/wire interconnect, designed to mate with the matching Micro-Fit 3.0 receptacle housing for harness assemblies in automotive, industrial, medical, and telecom equipment. Rated 8 A per circuit at 600 V, with 30.0 µinch gold plating on the mating contacts for repeated mating cycles and a UL94 V-0 liquid crystal polymer housing for flame retardance. For a 18-position header carrying power on all circuits, that is up to 144 A total across the connector, though real-world designs typically reserve several pins for lower-current signals or ground returns. The 3.00 mm pitch and row spacing define the PCB footprint — each pin occupies a 0.118-inch grid, which gives enough creepage for the 600 V rating without forcing an oversized board.","metaTitle":"Molex Micro-Fit 3.0 0430451802, 18-Pos Right-Angle Header","metaDescription":"Molex Micro-Fit 3.0 header 0430451802, 18-position dual-row, 3.00 mm pitch, 8 A per circuit, 600 V, gold mating contacts, shrouded 4-wall, board lock.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"0430451802","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":"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":"$4.9100","priceTiers":[{"qty":1,"price":"$4.91000","currency":"USD"},{"qty":10,"price":"$4.31800","currency":"USD"},{"qty":80,"price":"$3.43438","currency":"USD"},{"qty":1440,"price":"$2.84567","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5b79a4882032b964f94b5d8cad827dd8.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430451802/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of molex 0430451802?","answer":"The 0430451802 is rated 8 A per circuit at room temperature, with derating required above 25 °C per the product drawing."},{"question":"Is 0430451802 RoHS compliant?","answer":"Yes, the 0430451802 is ROHS3 Compliant."},{"question":"What connector mates with 0430451802?","answer":"This header mates with any Micro-Fit 3.0 receptacle housing (43025 series) that accepts the matching crimp terminals, using the locking ramp for retention."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/0430451802","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/0430451802 when reusing this data.
