G125-FS11605F2R

Overview

The Harwin G125-FS11605F2R is a Gecko-SL series female socket connector designed for surface mount technology. It features a 1.25 mm pitch with two rows of eight positions, totaling sixteen contacts. The component utilizes gold-plated phosphor bronze terminals housed in green polyamide insulation. Rated for 250 V and 2 A current, it operates within a temperature range of -65°C to +150°C. This vertical SMT header employs reverse fixing for secure board attachment.

Feature Summary

• Vertical surface mount configuration with reverse fixing mechanism
• Gold-plated phosphor bronze contacts for reliable signal transmission
• Green polyamide housing providing UL 94 V-0 flammability rating

Applications

• High-density board-to-board interconnections
• Power distribution modules requiring compact form factors
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify the specific suffix 'F2R' against official Harwin documentation to confirm the reverse fix orientation and tape-and-reel packaging format. Ensure compatibility with automated pick-and-place equipment due to the SMT design. Cross-reference the datasheet for precise reflow soldering profiles and storage conditions to maintain component integrity during assembly.

Selection Notes

Select this model when space constraints necessitate a low-profile vertical connection with secure mechanical locking. The reverse fix feature distinguishes it from standard SMT headers, offering enhanced stability during thermal cycling. Consider the 1.25 mm pitch and 2A rating to ensure adequate current capacity for the intended circuit load without exceeding thermal limits.

Part Context

This component belongs to the Harwin Gecko-SL family, which specializes in high-reliability, small-pitch connectors. The series supports various mounting styles and contact configurations, catering to demanding applications in aerospace, medical, and industrial sectors where consistent performance under stress is critical.
