Rated 8 A per contact with gold-on-mating-side and tin-on-post plating, it handles medium-current power and signal duty across automotive, industrial, medical, and telecom applications. The 8 A per-contact rating is the headline power spec — each contact carries enough current for a moderate DC rail or a cluster of signal lines, but the real duty is governed by the gold mating finish (15.0 µ\" on the mating side). Mates with the Micro-Fit 3.0 receptacle housing (sold separately) using the matching crimp terminal — the locking ramp engages with the receptacle's ramp to prevent accidental disconnection.","metaTitle":"Molex Micro-Fit 3.0 430452022, 20 Pos Header, 3mm Pitch, 8A","metaDescription":"Molex Micro-Fit 3.0 430452022 header, 20 positions, 3.00mm pitch, right-angle through-hole, gold mating finish, 8A per contact, 600V, locking ramp, board lock.","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":"430452022","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER R/A 20POS 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":"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":"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":"$8.29","priceTiers":[{"qty":1,"price":"$8.29000","currency":"USD"},{"qty":10,"price":"$7.25400","currency":"USD"},{"qty":80,"price":"$5.87213","currency":"USD"},{"qty":1296,"price":"$4.83588","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430452022/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 430452022?","answer":"Rated 8 A per contact at the stated operating temperature range.
