305-044-520-278

Edgeboard Connectors Overview

The EDAC 305-044-520-278 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features a dual-row configuration with 44 positions and a 3.96 mm pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with required polarizing key configurations. Ensure that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range before procurement. Confirm that the application environment remains within the -40°C to +105°C operating temperature limits. Cross-reference the 5 A current rating with actual load requirements to prevent thermal issues during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 44-position connection is required with a 3.96 mm pitch. The vertical panel mount style is suitable for chassis-based installations where space efficiency is prioritized. Consider the gold plating for corrosion resistance in demanding environments. Verify that the thermoplastic polyester housing meets the mechanical and thermal requirements of the specific assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are characterized by their robust construction and standardized dimensions. The series offers various position counts and mounting options to support diverse electronic packaging needs. The 305 series is widely used in applications requiring reliable high-density interconnections between circuit boards and backplanes.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 44 positions and 3.96 mm pitch, such as 305-044-520-202 or 305-044-520-268, provided they meet the same electrical and mechanical specifications.
