That current ceiling is typical for signal-level duty — think sensor inputs, I2C buses, or low-power actuator lines inside a control cabinet. ## SMT Assembly and Pick-and-Place The header is terminated by solder reflow — the SMT pads are held in place by solder retention features during wave or reflow. It also includes a pick-and-place surface, so it feeds straight into a standard SMT line without a manual placement step. The closest sibling is the B4B-ZR-SM4-TF, which shares the same 4-position, 1.50 mm pitch, and tin-plated contacts but omits the pick-and-place feature. If your line handles the part manually, the -TF variant is a direct drop-in; if you need pick-and-place, this -TFT version is the one.","metaTitle":"JST B4B-ZR-SM4-TFT(LF)(SN) ZH 4-Pin SMT Header, 1.5mm Pitch","metaDescription":"JST ZH series 4-position SMT header, 1.50mm pitch, shrouded with detent lock.
