Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct housing material and contact plating specifications. Confirm that the target application environment temperature remains within the component's operational limits. Check for any specific RoHS compliance requirements relevant to your region. Ensure PCB design matches the 3.96 mm pitch and required board thickness range for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this model when a high-temperature capable card edge connector is required for double-sided board connections. The 82-position count and 3.96 mm pitch define the spatial and electrical constraints. Consider the DAP housing material for its thermal properties. Verify that the through-hole mounting style aligns with the assembly process and mechanical stress requirements of the final product.

Edgeboard Connectors Part Context

This component belongs to the EDAC 837 series, which specializes in high-temperature card edge connectors. The series offers various position counts and configurations to support diverse industrial and automotive needs.
