125B-78C00

Edgeboard Connectors Overview

The ATTEND Technology 125B-78C00 is a surface-mount MXM 3.0 connector featuring 314 pins with a 0.50mm pitch. It utilizes a dual-row configuration and right-angle mounting for high-density PCIe applications. The component includes board guide and latch features, operates within -40°C to +85°C, and has a profile height of 7.8mm.

Edgeboard Connectors Feature Summary

• High-density PCIe solution supporting advanced server architectures
• Integrated board guide and latch mechanisms for secure connection
• Dual read-out configuration with solder termination

Edgeboard Connectors Applications

• Advanced server system architectures
• Industrial equipment requiring wide temperature operation
• MXM module interconnects

Edgeboard Connectors Procurement Notes

Verify the specific surface coating option required for your application, as multiple choices are available. Confirm that the 7.8mm profile height and right-angle SMT footprint align with your PCB design constraints. Ensure compatibility with MXM 3.0 standards before integration into high-density server systems.

Edgeboard Connectors Selection Notes

Select this part for applications demanding robust MXM connectivity with integrated latching. Consider the copper alloy contact material and solder termination method for reliable electrical performance. Evaluate the dual-row layout against space limitations in dense server environments.

Edgeboard Connectors Part Context

This component belongs to ATTEND's MXM connector series, designed for industrial use between -40°C and +85°C. It serves as a high-density interface for PCIe solutions, often paired with variants like the 125A-78C00 for different mounting or pin configurations.

Edgeboard Connectors Replacement Considerations

The 125A-78C00 is a documented variant within the same MXM series. Verify if alternative pin counts or profile heights are needed, as direct substitutes require matching MXM 3.0 specifications and mechanical dimensions.
