This is a fine-pitch, surface-mount connector designed for dense board-to-board or flex-to-board interconnects where space is tight — think compact handheld devices, camera modules, or battery management boards. This part is marked Obsolete. The 20 positions match a 20-circuit harness or a 20-pin board interface. The 0.091\" (2.30mm) height above board determines the z-height budget when mated with a JMC series header; you'll need the header's mated height to confirm the stack clearance. Gold contact finish handles repeated mating cycles better than tin, but without a specified cycle count, treat it as moderate-duty. It is a surface-mount termination — no through-holes, so the board must have SMT pads aligned to the 0.50mm pitch. The board guide feature helps locate the connector during pick-and-place, reducing tombstoning risk. The tape-and-reel packaging suits automated assembly lines.","metaTitle":"20R-JMCS-G-B-TF(NSA) JST JMC Receptacle, 0.50mm Pitch","metaDescription":"JST JMC series 20-position receptacle, 0.020\" (0.50mm) pitch, gold-plated contacts, SMT, 2.30mm height.
