Product details

The JAE 20P-JMDSS-G-1-TF(LF)(SN) is a 20-position plug from the JMD series, a board-to-board mezzanine connector family built around a 0.50mm pitch. Gold plating on the contacts handles the repeated mating cycles these assemblies see during test and final integration.

0.50mm pitch is the fine-pitch territory where board routing density and alignment tolerance become the limiting factors, not the contact current rating. At this spacing, the PCB trace escape between pads is tight — expect micro-via or HDI board layers if routing more than one signal per channel.

Frequently asked questions
