It uses a 0.118\" (3.00mm) pitch on both the row and position spacing, which gives a compact but serviceable footprint for routing power and signal traces. The header is surface-mount, right-angle, with a shrouded 4-wall housing that protects the male pins during handling and mating. Typical applications include automotive harnesses, industrial control panels, medical equipment, and telecom gear — any place where a locked, vibration-resistant wire-to-board connection is needed. ## Key Ratings and What They Mean for Your Build Rated 8 A per circuit at 600 V. The 8 A figure is per-contact under the rated temperature rise — it's a power interconnect, not a signal line, so size your traces and wire gauge accordingly. The 600 V rating on a 3.00 mm pitch gives enough creepage for industrial bus voltages and telecom power feeds without forcing an oversized board footprint. Tin plating on the mating surface (60.0 µin thick) is cost-effective for moderate mating cycles — think field-service connections, not daily unplugging. For high-cycle applications, the gold-plated variants in the same series are the better choice. The operating range of -40°C to 105°C covers automotive underhood and industrial cabinet environments. The UL94 V-0 housing means this header can go inside equipment that requires a flame-rated enclosure — a common spec for industrial and telecom gear. The board lock is included on the SMT version and is critical for reflow: it holds the header in place during soldering and takes the shear force from the cable strain after mating. ## Mating and Termination This header mates with any standard Micro-Fit 3.0 receptacle housing — the locking ramp on the shroud engages the receptacle latch to keep the pair mated under vibration. Termination is SMT solder to the PCB; the right-angle orientation routes the wire exit parallel to the board, which is essential when vertical clearance is tight inside an enclosure. The 10 circuits are fully loaded across two rows, so every position is active.","metaTitle":"Molex Micro-Fit 3.0 430451006 Header, 10 Circuits, 3mm Pitch","metaDescription":"Molex 430451006 Micro-Fit 3.0 header, 10 circuits, 3.00mm pitch, SMT right-angle, shrouded 4-wall, tin contacts, 8A, 600V, 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":"430451006","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 10POS 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":"10","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","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":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.14","priceTiers":[{"qty":1,"price":"$4.14000","currency":"USD"},{"qty":10,"price":"$3.64600","currency":"USD"},{"qty":100,"price":"$2.90030","currency":"USD"},{"qty":200,"price":"$2.90030","currency":"USD"},{"qty":1000,"price":"$2.40310","currency":"USD"},{"qty":2000,"price":"$2.32024","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fe12b6ab2d29dd5b49138d7785b3f9c0.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451006/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating and voltage rating of 430451006?","answer":"The 430451006 is rated 8 A per circuit at 600 V.
