It carries 18 positions loaded across two rows at the series-standard 0.118\" (3.00mm) pitch — matching the footprint for the mating receptacle housing. Rated 8A per circuit at 600V, with tin-on-tin contact finish at 60.0µin (1.52µm) on the mating side, suited for moderate-cycle applications where cost per position matters more than high-mating-cycle gold. ## Key features and deployment context The 4-wall shrouding and integrated locking ramp provide positive retention and pin protection in vibration-prone environments — the latch audibly clicks when fully mated, giving the harness builder a tactile confirmation. The glass-filled LCP housing carries a UL94 V-0 flammability rating and operates from -40°C to 105°C, covering under-hood automotive and industrial cabinet temperature profiles without derating the 8A per-circuit current. The 0.125\" (3.18mm) post length suits standard 1.6mm PCBs.","metaTitle":"Molex 0430451824 Micro-Fit 3.0 Header, 18 circuits","metaDescription":"Molex 0430451824 Micro-Fit 3.0 through-hole header, 18 positions, dual row, 0.118\" (3.00mm) pitch, rated 8A at 600V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Micro-Fit 3.0 43045","Features":"Board Guide, Board Lock","Packaging":"Tray","Shrouding":"Shrouded - 4 Wall","Part Status":"Active","Termination":"Kinked Pin, Solder","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","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.390\\\" (9.91mm)","Ingress Protection":"-","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","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0d721345d2d6d65d6196bb048814a0ce.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430451824/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and row count of 0430451824?","answer":"Dual-row header at 0.118\" (3.00mm) pitch, 18 positions total, all positions loaded."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/0430451824","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/0430451824 when reusing this data.
