The JST 30P4.0-JMCS-G-TF(N) is a 30-position plug from the JMC series, designed as a board-to-board interconnect with a tight 0.020" (0.50mm) pitch. It uses outer shroud contacts arranged in two rows and terminates via surface mount, making it suitable for high-density PCB stacking where the mated height is held to 4mm.
The 0.020" (0.50mm) pitch and 30-position count define the PCB footprint — a tight-pitch SMT layout that demands precise solder paste stencil alignment.
