It is a board-to-wire interconnect — the male pins mate with a Micro-Fit 3.0 receptacle housing to deliver power or signal from the PCB to a harness. The 8 A per circuit rating at 600 V puts this squarely in the power interconnect class: each contact can carry enough current for a small motor, a solenoid, or a DC-DC converter feed, not just a logic-level signal. The 8 A per circuit is the per-contact limit at the rated temperature rise; in practice, if all four circuits are loaded simultaneously in a warm enclosure, the total current through the header stays under 32 A before the housing temperature climbs. This header mates with any Micro-Fit 3.0 receptacle housing that matches the 4-circuit, dual-row layout. The male pins are square, kinked for retention in the housing, and terminate via through-hole solder. The base product number 043045 covers the series footprint, so any datasheet or drawing starting with that prefix applies to this variant.","metaTitle":"Molex 430450414 Micro-Fit 3.0 Header, 4 Pos, 8A","metaDescription":"Molex 430450414 Micro-Fit 3.0 header, 4 circuits, 3.00mm pitch, 8A per circuit, 600V, gold mating finish, shrouded 4-wall, locking ramp, UL94 V-0.","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":"430450414","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 4POS 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":"4","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":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.27","priceTiers":[{"qty":1,"price":"$2.27000","currency":"USD"},{"qty":10,"price":"$1.93200","currency":"USD"},{"qty":80,"price":"$1.59563","currency":"USD"},{"qty":2232,"price":"$1.21773","currency":"USD"},{"qty":6696,"price":"$1.11695","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430450414/alternatives.json"},"ai":{"faq":[{"question":"Is 430450414 RoHS compliant?","answer":"Yes, the 430450414 is ROHS3 Compliant per the lifecycle record."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430450414","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/430450414 when reusing this data.
