10139839-003LF

Edgeboard Connectors Overview

The Amphenol ICC (FCI) 10139839-003LF is a dual-sided card edge connector designed for through-hole mounting. It features 28 positions, configured as 20 signal and 4 power contacts per side, totaling 40 active contacts in the dual configuration. The connector utilizes copper alloy contacts with gold or GXT™ gold plating to ensure reliable conductivity. It is rated for a current of 9 A per contact and operates within a temperature range of -55°C to 105°C. The housing is constructed from black thermoplastic material, suitable for non-specified double-sided card applications with a thickness of 0.062 inches (1.57 mm).

Edgeboard Connectors Feature Summary

• Dual-sided female contact arrangement for secure board retention.
• Gold or GXT™ plated copper alloy contacts for enhanced corrosion resistance.
• Through-hole termination method ensuring robust mechanical stability.
• Integrated board lock feature for positive connection security.

Edgeboard Connectors Applications

• High-performance computing backplanes requiring high current capacity.
• Industrial control systems utilizing double-sided circuit boards.
• Telecommunications infrastructure equipment.
• Network switching hardware with specific card edge requirements.

Edgeboard Connectors Procurement Notes

Verify the exact ordering suffix and plating specification against the manufacturer's latest datasheet before procurement. Confirm that the application environment falls within the specified -55°C to 105°C operating temperature range. Ensure the PCB card thickness matches the 0.062-inch design parameter. Check for RoHS compliance status if required by project specifications. Cross-reference the part number with official distributor catalogs to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with high current rating is required. The 9 A current rating makes it suitable for power distribution alongside signal transmission. Consider the through-hole mounting style for applications needing higher mechanical strength than surface-mount options. Evaluate the GXT™ plating option for environments demanding superior wear resistance compared to standard gold finishes. Ensure compatibility with the target PCB stack-up and card thickness constraints.

Edgeboard Connectors Part Context

This connector belongs to the HPCE® series by Amphenol ICC (FCI), focusing on high-density interconnect solutions. The series is engineered for demanding applications where reliability and signal integrity are critical. The 10139839-003LF specifically addresses the need for robust power and signal connections in compact form factors.
