70-Position SMT Receptacle for Dense Mezzanine Stacks
The JST 70R-JMDSS-G-1-TF is a 70-position receptacle from the JMD series, designed for board-to-board mezzanine interconnects where routing density and a low stack height matter. The SMT footprint and solder retention features keep it anchored through reflow, and the 0.122" (3.10mm) height above board lets it fit into tight z-height budgets. Typical applications include compact consumer electronics, portable devices, and internal board stacking where every millimeter counts.
Stack Height Options and Board Layout Fit
Compared to the 80-position sibling (80R-JMDSS-G-1-TF), the 70-position version saves 10 signals worth of routing area at the same pitch and stack height — a straight position-count decision for the BOM.
