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.","metaTitle":"JST BM40B-SRDS-G-TF(LF)(SN) SHD Header 40 Pos 1mm Pitch SMT","metaDescription":"JST SHD series header, 40 positions, 1.00 mm pitch, gold-plated male pins, shrouded 4-wall, SMT, UL94 V-0.
