Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to ensure compatibility with required board thicknesses and mounting configurations. Confirm that the gold plating specification meets the intended application's conductivity requirements. Check for RoHS compliance status as per the latest environmental declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required for standard thickness PCBs. Ensure the design accommodates the 0.156-inch pitch and dual-row layout. Consider the panel mount requirement during mechanical design. Verify thermal performance needs against the specified operating temperature range to guarantee long-term reliability in the target environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting options. The 305-082 variant provides a high-density solution compared to lower-position models like the 305-018 or 305-038. It shares common series characteristics such as thermoplastic insulation and gold contact plating.

Edgeboard Connectors FAQ

What is the nominal thickness of the printed circuit board accepted by this connector?

The connector is designed to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm).
