It carries an 8 A per circuit current rating at a 3.00 mm pitch, with a 600 V voltage rating — the 8 A figure means each contact is sized for power distribution, not just signal-level current, so this header suits DC rail feeds and multi-circuit power delivery in harness assemblies. The tin-plated mating contacts with 100.0 µ\" thickness are a heavy-duty power finish: they handle the 8 A current with low contact resistance but are rated for fewer mating cycles than gold-plated alternatives — typical for permanent or semi-permanent harness connections where the header is soldered to the board and the receptacle is crimped to the wire harness. The 22 positions in a dual-row layout with 0.118\" (3.00 mm) row spacing define the PCB footprint — a 2 x 11 grid. The through-hole posts are 0.125\" (3.18 mm) long, suited for standard 1.6 mm PCBs.","metaTitle":"Molex Micro-Fit 3.0 430452212, 22-Pos Header, 8 A, 600 V","metaDescription":"Molex Micro-Fit 3.0 430452212 22-position dual-row header, 3.00 mm pitch, 8 A per circuit, 600 V, through-hole, tin-plated, active production, RoHS3.","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":"430452212","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 22POS 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":"22","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":"$5.49","priceTiers":[{"qty":1,"price":"$5.49000","currency":"USD"},{"qty":10,"price":"$4.82700","currency":"USD"},{"qty":80,"price":"$3.83988","currency":"USD"},{"qty":1152,"price":"$3.18162","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/74101370f82c836efeaf1b86302c438e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430452212/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 430452212?","answer":"The 430452212 is rated 8 A per circuit at the stated temperature rise, making it a power-grade interconnect suitable for DC rail feeds and multi-circuit power delivery."},{"question":"Is 430452212 RoHS compliant?","answer":"Yes, the 430452212 is RoHS3 compliant, confirming it meets the latest EU restriction of hazardous substances directive."},{"question":"Does 430452212 have a locking ramp?","answer":"Yes, the 430452212 uses a locking ramp fastening type that provides positive retention against vibration — a key feature for automotive and industrial harness applications."},{"question":"What is the pitch of 430452212?","answer":"The 430452212 has a 3.00 mm (0.118\") mating pitch with the same 3.00 mm row spacing, matching the standard Micro-Fit 3.0 footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430452212","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/430452212 when reusing this data.
