It mates with the corresponding SH/SR crimp receptacle for a board-to-wire connection. Tin is a good fit for low-cycle, cost-sensitive applications — expect a few hundred mating cycles before contact resistance drifts. The 4.9 mm mated stack height is the z-height from the PCB top to the mating receptacle face — plan your enclosure clearance accordingly. RoHS compliant. No official second-source cross-reference from JST; the closest functional equivalent is the BM03B-SRSS-TB (same pinout, same pitch, same current rating, same 4.9 mm stack height) but without the pick-and-place feature tape.","metaTitle":"JST BM03B-SRSS-TBT(LF)(SN) SH/SR Header, 3 Pos, 1 mm Pitch","metaDescription":"JST SH/SR series 3-position shrouded header, 1.00 mm pitch, SMT, tin-plated contacts rated 1 A at 50 V.
