The 3.00 mm pitch and 0.125\" (3.18 mm) solder-tail length suit standard through-hole PCB layouts. The housing is black UL94 V-0 LCP, rated from -40°C to 105°C, and the contacts are tin-plated (60.0 µin / 1.52 µm on the mating surface). ## Locking Ramp and Full Shroud for Vibration Resistance A built-in board guide aids alignment during automated assembly. This header is specified for automotive, general-purpose industrial, medical, and telecommunications equipment. The UL94 V-0 rating satisfies flame-retardant requirements for equipment inside enclosures.","metaTitle":"Molex Micro-Fit 3.0 430452027, 20-Pos 3mm Header, 8A","metaDescription":"Molex 430452027 Micro-Fit 3.0 header, 20 circuits, dual-row 3.00 mm pitch, 8 A per circuit at 600 V, tin-plated, shrouded 4-wall, locking ramp.","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":"430452027","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 20POS 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":"20","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":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.55","priceTiers":[{"qty":1,"price":"$5.55000","currency":"USD"},{"qty":10,"price":"$4.88000","currency":"USD"},{"qty":80,"price":"$3.88175","currency":"USD"},{"qty":1296,"price":"$3.21633","currency":"USD"},{"qty":2592,"price":"$2.99452","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430452027/alternatives.json"},"ai":{"faq":[{"question":"What is the mating receptacle for molex 430452027?","answer":"The 430452027 mates with a Micro-Fit 3.0 receptacle housing of the same circuit count and pitch.
