Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct pin count and termination type. Confirm RoHS compliance status and environmental ratings prior to integration. Cross-reference datasheet specifications for mechanical dimensions and thermal limits to guarantee compatibility with target assembly requirements.

Edgeboard Connectors Selection Notes

Select this model when high channel density is required in a compact form factor. The 3.96 mm pitch balances spacing needs with signal integrity. Ensure the mating card edge thickness aligns with the connector's acceptance range. Consider the straight orientation for direct board insertion versus angled variants if space constraints dictate otherwise.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options.
