Rated 0.2 A per contact (0.5 A peak) at 30 V – this is a signal-level interconnect, not for power delivery. ## Solder retention and shrouded walls for reliable assembly RoHS non-compliant per the listing – verify your assembly's regulatory requirements before committing. ## Position count contrast within the SUR series The 12-position BM12B-SURS-TF shares the same 0.80 mm pitch, stack height, and tin-plated contacts as the 10-position BM10B-SURS-TF(LF)(SN) and the 8-position BM08B-SURS-TF – the only difference is circuit count. If your BOM calls for 12 circuits, this is the correct member; the 10- or 8-position siblings will not fit a 12-way mating receptacle.","metaTitle":"JST BM12B-SURS-TF Header – 0.80 mm Pitch, 12 Pos, SMT","metaDescription":"JST SUR series SMT header, 12 circuits, 0.80 mm pitch, shrouded 4-wall, solder retention.
