All 20 positions are loaded, so the pinout matches a 20-contact receptacle one-to-one. ## Material and Environmental Ratings The operating temperature range spans -65°C to 125°C, covering most industrial and automotive interior environments. Contact material is phosphor bronze with a tin post finish (78.7 µinch) for reliable solderability.","metaTitle":"77311-846-20LF BERGSTIK Header, 20-Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 77311-846-20LF BERGSTIK unshrouded header, 20 positions, 0.100\" pitch, 3 A per contact, gold mating finish.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK®","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"77311","Insulation Material":"Thermoplastic","Number of Positions":"20","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.117\\\" (2.97mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.535\\\" (13.59mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.318\\\" (8.08mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3788","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 77311-846-20LF available via RFQ confirmation?","answer":"The 77311-846-20LF is an active-production part."},{"question":"Is 77311-846-20LF shrouded or unshrouded?","answer":"It is an unshrouded header.
