Rated 1 A per contact at 50 V, it mounts via surface-mount solder termination and includes a shrouded 4-wall housing with solder retention features to hold the part in place during reflow. ## What the specs mean for the board layout The 1.00 mm pitch drives a compact board footprint — the single-row layout keeps the connector width to the insulation body's 0.167\" (4.25 mm) height, leaving room for trace routing under the part. The push-pull fastening type and tin-plated mating contacts suit low-cycle, low-current signal duty; the UL94 V-0 nylon housing meets the flammability rating required inside enclosed equipment. Mated stacking height is 4.9 mm — this sets the z-height budget for the cable-to-board interface in a space-constrained assembly.","metaTitle":"JST BM09B-SRSS-TB(LF)(SN) SH/SR Header, 9-Pos 1.00mm","metaDescription":"JST SH/SR header BM09B-SRSS-TB(LF)(SN): 9 positions, single row, 1.00 mm pitch, 1 A, 50 V, tin-plated contacts, SMT, shrouded 4-wall, solder retention.","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":"SH/SR","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Push-Pull","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":"0.167\\\" (4.25mm)","Ingress Protection":"-","Base Product Number":"BM09B-SR","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"9","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"4.9mm","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":"$0.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/01a3d0422a428094e98b60769fffa9d7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the SH/SR series?","answer":"The SH/SR series includes headers in other position counts at the same 1.00 mm pitch.
