Key features include a 3.00 mm pitch, 8 A per circuit current rating, 600 V voltage rating, gold-plated mating contacts (15.0 µin), a shrouded 4-wall housing with a locking ramp, and integrated board locks for through-hole solder attachment. The 8 A per circuit rating means each pin can carry moderate power — think a DC rail or a motor drive line — not just a signal. The 600 V rating provides enough creepage for industrial or telecom power distribution at this pitch. Applications span automotive, general purpose, industrial, medical, and telecommunications equipment — typical for a Micro-Fit 3.0 header used in harness assemblies inside enclosures, on board edges, or in vibration-prone locations where the locking ramp and board lock provide mechanical security. The 3.00 mm pitch and 0.118\" row spacing set the board footprint — a dual-row layout that packs 12 circuits into a compact edge length. The 0.125\" (3.18 mm) solder tail length is standard for through-hole boards of typical thickness. The UL94 V-0 LCP housing handles the thermal load of 8 A per circuit across all 12 positions, with the glass-filled material providing dimensional stability through reflow or wave solder. ## Comparison with the 10-Circuit Sibling Against the 10-circuit 430451221, the 430451222 adds two positions at the same 3.00 mm pitch and dual-row layout. The 12-circuit version matches a 12-position BOM line; the 10-circuit sibling fits a 10-position requirement. All other key specs — 8 A per circuit, 600 V, gold plating, board lock, locking ramp, UL94 V-0 — are identical across the two variants.","metaTitle":"Molex Micro-Fit 3.0 430451222, 12-Circuit Right-Angle Header","metaDescription":"Molex 430451222 Micro-Fit 3.0 dual-row 12-position right-angle header, 3.00 mm pitch, 8 A per circuit, 600 V, gold-plated contacts, shrouded, board lock, 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":"430451222","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER R/A 12POS 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","Insulation Color":"Black","Insulation Height":"0.290\\\" (7.37mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"12","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","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":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.64","priceTiers":[{"qty":1,"price":"$4.64000","currency":"USD"},{"qty":10,"price":"$4.08400","currency":"USD"},{"qty":80,"price":"$3.24850","currency":"USD"},{"qty":1008,"price":"$2.69161","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dfff01b2e2ed78f9b97db4b2de03830c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430451222/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 430451222?","answer":"The 430451222 is rated 8 A per circuit at the stated temperature rise. This is a power-class rating — each pin can carry a moderate DC rail or motor drive current, not just a signal."},{"question":"Is 430451222 a right-angle header?","answer":"Yes, the 430451222 is a through-hole, right-angle header. The pins exit parallel to the PCB, making it suitable for board-edge mounting or space-constrained enclosures."},{"question":"What is the difference between 430451222 and 430451221?","answer":"The 430451222 has 12 circuits; the 430451221 has 10 circuits. Both share the same 3.00 mm pitch, dual-row layout, 8 A per circuit, 600 V rating, gold-plated contacts, board lock, locking ramp, and UL94 V-0 housing. Choose the position count that matches your circuit count."},{"question":"Does 430451222 have a locking ramp?","answer":"Yes, the 430451222 uses a locking ramp fastening type, which provides a positive audible latch when mated with the matching receptacle housing.
