Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with your design requirements. Ensure that the 3.96 mm pitch and 78-position count match your PCB layout specifications. Confirm that the panel mount style and solder pin termination align with your assembly processes. Cross-reference the thermal ratings and material composition with your environmental constraints before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, double-sided connection is required with a 3.96 mm pitch. The 305 series offers robust mechanical stability for panel-mounted applications. Consider the gold plating for corrosion resistance in demanding environments. Verify that the 1.57 mm PCB thickness tolerance fits your board design constraints and that the vertical orientation matches your chassis layout requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series provides various position counts and termination options for diverse electronic applications. The 305-078 variant specifically addresses needs for higher density connections while maintaining the established reliability standards of the series.
