PH series, B9B-PH-SM4-TBT(LF)(SN), Board to Cable/Wire, 9 Positions, 2.00mm Pitch, Surface Mount, Tin Mating Finish, Shrouded 4-Wall, Detent Lock, UL94 V-0, RoHS Compliant, Active","salesMarkdown":"## Active Production — JST PH Series 9-Position SMT Header JST's B9B-PH-SM4-TBT(LF)(SN) is an active-production header from the PH series, carrying a 2.00mm pitch and 9 positions in a single row. It is a surface-mount, shrouded 4-wall design with a detent lock for positive mating retention. The 8.6mm mated stack height and 3.30mm mating pin length define the z-height budget for the board-to-wire interface. ## SMT Assembly and Packaging Options This header is surface-mount with pick-and-place and solder retention features, making it compatible with automated assembly. RoHS compliant per JST's LF (lead-free) suffix in the order code. The part is quoted to order — no stock-holding claim, but we can pull from multiple supply channels.","metaTitle":"B9B-PH-SM4-TBT(LF)(SN) JST PH Series 9-Pin SMT Header 2mm","metaDescription":"JST PH series 9-position SMT header, 2.00mm pitch, 2A, 100V, tin plating, shrouded 4-wall, active production.
