0.80 mm pitch SMT header for tight board-to-cable routing
The BM12B-SURS-TF: JST SUR series header, 12 positions at 0.80 mm pitch, surface-mount with a shrouded 4-wall housing that protects the contacts during mating. 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.
