Vertical mounting keeps the cable standing upright off the board, which helps in tight enclosures where a right-angle connector would crowd the edge. RoHS compliant. ## Position count delta vs 30-position sibling Compared to the 30-position 30FMN-BMT-A-TF, this 40-position version adds ten circuits in the same 1.00 mm pitch and same 5.10 mm height above board. All other ratings — 0.5 A, 50 V, LIF, tin finish, UL94 V-0 — are identical across the FMN vertical SMD family.","metaTitle":"JST 40FMN-BMT-A-TF(LF)(SN) – 40-Pos 1mm Pitch FFC Connector","metaDescription":"JST FMN series FFC connector, 40 positions, 1.00 mm pitch, vertical SMD, LIF, tin contacts, UL94 V-0.
