Pick-and-place features and solder retention pads enable automated assembly and anchor the header against shear forces from cable strain. ## What the 1 A Rating Means for Signal Duty This is a signal-level connector — fine for logic-level power, sensor inputs, or data lines. The 50 V rating covers typical low-voltage industrial and consumer bus voltages. For higher current needs, step up to a wider-pitch series like JST's SH or PH families. Mates with JST SHD series crimp-style receptacles (sold separately). The 1.00 mm pitch requires a matching PCB footprint — confirm the pad layout against the product drawing before committing the board.","metaTitle":"SM50B-SRDS-G-TF (LF)(SN) SM50B-SRDS-G-TF (LF)(SN) JST","metaDescription":"JST SM50B-SRDS-G-TF SHD series header, 50 positions, 0.039\" (1.00 mm) pitch, right-angle SMD, gold-plated pins, 1 A, 50 V.
