1.00 mm Pitch, 40-Position SMT Header for Dense Board-to-Cable Interconnects
The BM40B-SRDS-G-TF(LF)(SN): This JST SHD series header packs 40 circuits into a dual-row, 1.00 mm pitch footprint — the tight spacing saves board real estate but demands careful soldering alignment during reflow. With a mated stack height of 6.3 mm, it fits within tight z-height budgets typical of portable or panel-mount devices.
Terminated by solder reflow, this header includes pick-and-place features and solder retention to keep it aligned during the reflow cycle.
The BM40B-SRDS-G-TF(LF)(SN) is the 40-position version of the SHD series. The closest sibling, BM40B-SRDS-G-TF, shares the same 40 positions, 1.00 mm pitch, gold plating, and natural housing — the only difference is the (LF)(SN) suffix confirming RoHS compliance on this variant. The BM40B-SRDS-A-G-TF adds a board guide feature for alignment during assembly, while the BM50B-SRDS-G-TF offers 50 positions for higher-density needs — both otherwise match the same pitch, current, and voltage ratings.
