Unshrouded design means the square pins are exposed; the mating half provides the keying and polarization. This keeps the header footprint small and the board-edge clearance tight. ## Current, Temperature, and Plating Rated 3 A per contact with tin plating at 78.7 µinch (2.00 µm) on both the mating face and the solder post. Tin is cost-effective for low-cycle signal duty — expect a few hundred mating cycles before contact resistance starts to drift. The UL94 V-0 thermoplastic housing holds its flame rating across that range. Overall contact length is 0.465\" (11.81 mm), giving a 0.260\" (6.60 mm) mating pin that engages the receptacle contact fully. Push-pull fastening — no latch, so the header relies on the receptacle's retention for vibration resistance. In high-shock environments, pair it with a locking receptacle or add a wire-to-board strain relief.","metaTitle":"77313-427-12LF BERGSTIK Header, 12 Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 77313-427-12LF BERGSTIK® unshrouded header, 12 positions, 0.100\" (2.54 mm) pitch, 3 A per contact, tin plating, through-hole.","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 or Cable","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","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":"77313","Insulation Material":"Thermoplastic","Number of Positions":"12","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.105\\\" (2.67mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"0.465\\\" (11.81mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.260\\\" (6.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"78.7µin (2.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4981","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 77313-427-12LF unshrouded or shrouded?","answer":"Unshrouded — the male pins are exposed.
