Board-to-Board Fit and Footprint
The 22R-JED(LF)(SN) is a 22-position, dual-row female socket receptacle from JST's JED series, designed for board-to-board stacking with a 1.25 mm mating pitch and 2.00 mm row spacing. Tin-plated contacts on phosphor bronze base carry 1 A per circuit at 50 V, adequate for signal-level and low-power interconnects where the mating cycle count stays under 100.
The bulk package suits both prototype and low-to-medium volume builds.
The through-hole solder termination is compatible with standard wave-solder processes. The 2.00 mm post length provides adequate solder fillet height on a typical 1.6 mm PCB.
