Termination is a hybrid — surface mount for the board-side attachment, with screw-clamp wire termination for the cable side. This suits applications where the header is soldered to a PCB but field wiring is done via a screw terminal rather than a crimp-and-poke contact. ## Selection Context: Where This Fits in the Series The 2119370003 is the 2-position member of the Coeur PowerWize 211937 series. At 120 A per circuit and 300 V, it is a dedicated power header — not a signal or mixed-use part. The 2-position count means it serves as a single-pair power input or output on a board, often paired with a mating receptacle that accepts the same 120 A rating. The 0.750\" row spacing is fixed across the series, so the footprint is consistent if you later need a higher position count in the same family.","metaTitle":"Molex Coeur PowerWize 2119370003 Header, 2 Pos, 120 A","metaDescription":"Molex 2119370003 Coeur PowerWize header, 2 circuits, 2 rows, 120 A per circuit, 300 V, silver-plated contacts, SMT, shrouded, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Coeur PowerWize 211937","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Style":"Board to Cable/Wire","title":"2119370003","Series":"Coeur PowerWize 211937","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Screw","description":"CONN HEADER SURFACE MOUNT 2POS","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Voltage Rating":"300V","Contact Material":"Copper Alloy","Insulation Color":"Blue","Insulation Height":"1.562\\\" (39.66mm)","Base Product Number":"211937","Insulation Material":"Polyester","Number of Positions":"2","Row Spacing - Mating":"0.750\\\" (19.05mm)","Contact Finish - Post":"Silver","Current Rating (Amps)":"120A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Silver","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.9","priceTiers":[{"qty":1,"price":"$21.90000","currency":"USD"},{"qty":24,"price":"$18.93792","currency":"USD"},{"qty":96,"price":"$16.21542","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6b5f966efb6d63d10c05834f2ef6fc58.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2119370003/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating per circuit for 2119370003?","answer":"Each circuit is rated 120 A, making this a bus-level power interconnect suitable for main DC rails or high-current distribution."},{"question":"Where can I buy 2119370003 and how is it quoted?","answer":"The 2119370003 is sourced and quoted to order against an RFQ through independent distribution.
