305-022-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-207 is a standard card edge connector from the 305 series, designed for dual female mating with unassigned double-sided circuit cards. It features 22 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The unit utilizes copper alloy contacts with gold plating and employs a solder lug termination method. Designed for panel mounting in a vertical orientation, it accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and flange specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through current manufacturer datasheets. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components. Validate that the selected variant matches the required panel mounting constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 3.96 mm pitch is required for vertical panel integration. Ensure the application environment stays within the specified -40°C to +105°C operational range. Verify that the target circuit board thickness falls between 1.37 mm and 1.78 mm for proper contact engagement. Consider the solder lug termination requirement for panel mounting versus PCB surface mount alternatives.
