305-030-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-030-521-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 30 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating and utilize a solder pin termination type. Rated for 5 A continuous current, it supports board thicknesses between 1.37 mm and 1.78 mm. The housing is constructed from green thermoplastic polyester, ensuring an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB stack-up dimensions before procurement. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the Mouser or DigiKey part numbers with the original datasheet to avoid ordering errors due to similar series variants.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted applications. The 30-position count suits moderate-density signal routing needs. Consider the 5 A current rating and wide temperature range for demanding operational environments. Verify that the target circuit board thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical engagement.
