Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact spacing and plating specifications match project requirements. Ensure compatibility with the target PCB thickness limits defined in the datasheet. Confirm that the dual-edge design aligns with the mechanical assembly constraints of the host enclosure. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required for dual-edge cards. The 1.27 mm pitch offers a balance between density and manufacturability. Consider the operating temperature range and material flammability ratings for environmental compliance. Evaluate the mounting style and termination method against the available PCB real estate and assembly processes.
