It uses a 1.50 mm pitch and surface-mount termination, with a shrouded 4-wall design that protects the pins and guides the mating female housing into alignment. ## Rated for signal-level current ## Board-fit and stack height The natural (off-white) color is standard for the ZH series. ## SMT vs through-hole: same pitch, different stack The through-hole sibling B3B-ZR has the same 1.50 mm pitch, 3 positions, and 1 A rating, but its mated stack height is 5.6 mm versus 6.4 mm for the SMT version. The through-hole part also lacks the solder retention feature. If your board assembly is wave-solder only, the through-hole version is the direct fit; for reflow, the SM4-TF is the correct choice.","metaTitle":"B3B-ZR-SM4-TF JST ZH Series 1.50 mm Pitch 3-Pin SMT Header","metaDescription":"JST ZH series 3-position SMT header, 1.50 mm pitch, 1 A, 50 V, detent lock, shrouded 4-wall.
