It carries tin-plated mating contacts rated 1 A at 50 V and mounts surface-mount with solder termination; the mated stack height is 7.3 mm. ## Locking ramp and shrouding The four-wall shroud and locking ramp protect the contacts from mis-mating and keep the pair locked under cable strain — the ramp engages audibly on mate and releases with a pull tab on the receptacle side. Pick-and-place compatible with a solder retention feature on the SMT tails, so it holds position during reflow without secondary hand-soldering.","metaTitle":"JST GH BM12B-GHS-TBT(LF)(SN)(N) Header, 12-Pos 1.25mm","metaDescription":"JST GH header BM12B-GHS-TBT(LF)(SN)(N): 12 positions, single row, 1.25 mm pitch, 1 A, 50 V, tin mating contacts, SMT, shrouded with locking ramp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"GH","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Pick and Place, Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Outer Shroud Contact","Contact Shape":"Rectangular","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.049\\\" (1.25mm)","Product Status":"Active","Voltage Rating":"50V","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Natural","Insulation Height":"0.159\\\" (4.05mm)","Ingress Protection":"-","Base Product Number":"BM12B-GH","Insulation Material":"Polyamide (PA9T), Nylon 9T","Number of Positions":"12","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"7.3mm","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a75cf03668291e2e02e3c13e7999bcd9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Who supplies BM12B-GHS-TBT(LF)(SN)(N) and how is it quoted for volume purchases?","answer":"Tape & Reel and Cut Tape packaging options are available."},{"question":"What is BM12B-GHS-TBT(LF)(SN)(N)'s listed style?","answer":"Board to Cable/Wire — a header that mates with a GH-series receptacle on a discrete-wire harness."},{"question":"What is BM12B-GHS-TBT(LF)(SN)(N)'s listed series?","answer":"GH series from JST Sales America Inc."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/jst/BM12B-GHS-TBTLFSNN","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/jst/BM12B-GHS-TBTLFSNN when reusing this data.
