305-048-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-204 is a standard card edge connector from the 305 series, designed for dual-edge female mating applications. It features 48 positions with a 0.156-inch (3.96 mm) pitch and supports board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and half-beam contact types. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's ordering guide to confirm exact plating thickness and material specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required board thickness tolerance for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm range. Consider the 5 A current rating and operating temperature limits for environmental suitability. Compare against other 305 series variants if different position counts or mounting styles are needed.

Edgeboard Connectors Part Context
