Contact Rating and Plating: What 2 A and 30 µinch Gold Mean
The 57102-G08-05LF: The 30 µinch gold GXT™ on the mating face supports 500+ mating cycles minimum, making it a good fit for field-serviceable boards where the connector is cycled during maintenance. The post finish is 78.7 µinch tin, which solders cleanly and provides a reliable board-level joint.
