The 0.450\" (11.43 mm) overall contact length includes the mating pin and the solder post, giving a total board stand-off of about 0.100\" (2.54 mm) from the PCB surface to the bottom of the insulator. The header ships in bulk packaging, which is typical for through-hole components — no tape-and-reel, so plan for hand-loading or tube feeding on the assembly line.","metaTitle":"77313-418-20LF BERGSTIK® Header 20 Pos 2.54 mm Unshrouded","metaDescription":"77313-418-20LF Amphenol ICC (FCI) BERGSTIK® header, 20 positions, 0.100\" (2.54 mm) pitch, unshrouded, through-hole, tin-plated, 3 A per contact.","metaKeywords":null},"attributes":{"series":"BERGSTIK®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board or Cable","Series":"BERGSTIK®","Package":"Bulk","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":"20","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"0.450\\\" (11.43mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.230\\\" (5.84mm)","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":"$0.7600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.63800","currency":"USD"},{"qty":100,"price":"$0.57330","currency":"USD"},{"qty":500,"price":"$0.46904","currency":"USD"},{"qty":1000,"price":"$0.41693","currency":"USD"},{"qty":5000,"price":"$0.36481","currency":"USD"},{"qty":10000,"price":"$0.34657","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the 77313-418-20LF and check availability?","answer":"The 77313-418-20LF is sourced through independent distribution.
