Rated 1 A per contact at 50 V, the header uses tin-plated mating contacts and mounts via surface-mount solder termination. The 1.00 mm pitch and 7.8 mm mated stacking height suit dense board layouts. ## Position count and footprint fit The 12-position BM12B-NSHSS-TBT (LF)(SN) sits in the NSH series alongside other position counts at the same 1.00 mm pitch. The single-row layout and 7.8 mm mated stack height are common across the series — match the position count to the circuit count on the board. ## Housing and temperature range The header uses a polyamide (nylon) housing rated UL94 V-0 and operates from -25°C to 85°C. The shrouded 4-wall design with latch holder protects the contacts and locks the mating cable plug in place.","metaTitle":"JST NSH BM12B-NSHSS-TBT (LF)(SN) Header, 12 Pos, 1.00mm","metaDescription":"JST NSH header BM12B-NSHSS-TBT (LF)(SN): 12 positions, single row, 1.00 mm pitch, 1 A, 50 V, tin-plated contacts, SMT, shrouded with latch holder.","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":"NSH","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Pick and Place, Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"-","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.039\\\" (1.00mm)","Product Status":"Active","Voltage Rating":"50V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.236\\\" (6.00mm)","Ingress Protection":"-","Base Product Number":"BM12B-NS","Insulation Material":"Polyamide (PA), Nylon","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":"7.8mm","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":"$1.1400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d9f935fd9c006f1b0df83d59dc99aeb6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mated stack height of this header?","answer":"The mated stacking height is 7.8 mm, measured from the board surface to the top of the mated connector pair."},{"question":"What compliance ratings does the housing carry?","answer":"The polyamide housing is rated UL94 V-0 for flammability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/jst/BM12B-NSHSS-TBT-LFSN","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-NSHSS-TBT-LFSN when reusing this data.
