The 9.8mm mated stack height keeps the assembly compact for tight enclosures. Termination is press-fit, solder – the square pins go through the plated holes and are wave-soldered. ## Position Count vs the 13-Circuit Sibling The closest peer in the XH series is the B13B-XH-A (and its LF(SN) variant) – identical 2.50mm pitch, same 3A/250V rating, same shrouded 4-wall and detent lock. The only difference is 13 positions vs 12.","metaTitle":"JST B12B-XH-A(LF)(SN) Header – 12 Pos, 2.5mm Pitch","metaDescription":"JST XH series header, 12 circuits, 2.50mm pitch, 3A, 250V, shrouded, detent lock, UL94 V-0, RoHS.
