Gold-plated mating contacts (30.0µin / 0.76µm) and a shrouded 4-wall housing with locking ramp provide secure retention for power and signal duty in general-purpose, medical, military, and telecommunications equipment. ## Board lock and right-angle mounting Through-hole right-angle mounting with integrated board locks holds the header in place during wave solder — the 0.125\" (3.18mm) post length suits standard PCB thickness. The 0.118\" (3.00mm) pitch and single-row layout keep the board footprint compact; the UL94 V-0 LCP housing resists process temperatures.","metaTitle":"Molex 0436500405 Micro-Fit 3.0 Header, 4-Pos 3.00mm","metaDescription":"Molex Micro-Fit 3.0 header 0436500405: 4 positions, single row, 3.00 mm pitch, gold mating contacts, through-hole right-angle, shrouded with locking ramp.","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 43650","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose, Medical, Military, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.118\\\" (3.00mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.172\\\" (4.37mm)","Ingress Protection":"-","Base Product Number":"043650","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"-","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":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2176","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8d04728271b0a5f00995054acb9466e5.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/0436500405/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Molex provide for 0436500405?","answer":"The housing carries a UL94 V-0 flammability rating.
