This dual-plating strategy is standard for BERGSTIK headers: the gold side handles repeated mating cycles, and the tin side ensures reliable solder-joint wetting during wave or hand-soldering.","metaTitle":"Amphenol FCI 55101-G1111LF BERGSTIK Header, 11-Pos","metaDescription":"Amphenol FCI BERGSTIK 55101-G1111LF 11-position unshrouded header, 0.100\" (2.54 mm) pitch, 5 A per contact, gold GXT mating finish, through-hole right-angle","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"55101-G1111LF","Series":"BERGSTIK®","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.140\\\" (3.56mm)","Base Product Number":"55101","Number of Positions":"11","Contact Finish - Post":"Tin","Contact Length - Post":"0.090\\\" (2.29mm)","Current Rating (Amps)":"5A","Contact Finish - Mating":"Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","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":"$0.6231","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5df463f350e91e65e23bd6425bccdf67.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/55101-G1111LF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of 55101-G1111LF?","answer":"The 55101-G1111LF is rated 5 A per contact.
