It is a through-hole, right-angle mounted header with a shrouded 4-wall housing and a locking ramp for secure mating. The 3.00mm pitch and 0.118\" row spacing give enough creepage for the 600V rating without forcing an oversized board footprint. Rated 8A per circuit at 600V, this header suits power distribution in automotive, industrial, medical, and telecom equipment. The UL94 V-0 liquid crystal polymer (LCP) housing holds up in enclosed assemblies where flame rating is required. The locking ramp provides an audible click when fully seated.","metaTitle":"Molex Micro-Fit 3.0 0430451222 Header, 12-Circuit","metaDescription":"Molex 0430451222 Micro-Fit 3.0 header, 12 positions, 3.00mm pitch, 8A, 600V, gold-plated contacts, through-hole right-angle, active production.","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 Lock","Packaging":"Tray","Shrouding":"Shrouded - 4 Wall","Part Status":"Active","Termination":"Solder","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","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.290\\\" (7.37mm)","Ingress Protection":"-","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","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","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":"$4.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/dfff01b2e2ed78f9b97db4b2de03830c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0430451222/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of molex 0430451222?","answer":"The mating pitch is 0.118\" (3.00mm), with the same 0.118\" row spacing between the two rows."},{"question":"What is the current rating of molex 0430451222?","answer":"The header is rated 8A per circuit at 600V.
