G125-FS12605F3R

Overview

The Harwin G125-FS12605F3R is a Gecko-SL series power-to-board connector featuring a 1.25 mm pitch and 26 positions in a dual-row configuration. It utilizes surface-mount technology with solder termination and female socket contacts. The component supports a current rating of 2 A and operates within a temperature range of -65 C to +150 C. Constructed with beryllium copper contacts gold-plated for conductivity, the housing is green nylon. This vertical SMT header includes reverse fixing features for secure board attachment.

Feature Summary

• Vertical surface-mount design with reverse fixing mechanism for enhanced stability
• Gold-plated beryllium copper contacts ensure reliable electrical performance
• High-temperature resistant nylon housing suitable for demanding environments

Applications

• Power distribution in compact electronic assemblies
• Interconnection in industrial control systems
• Consumer electronics requiring high-density power connections

Procurement Notes

Verify the specific ordering suffix 'R' confirms tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with automated pick-and-place equipment due to the surface-mount form factor. Cross-reference the full part number against distributor catalogs to avoid confusion with similar variants lacking the reverse fix feature.

Selection Notes

Select this component for applications requiring a low-profile, high-reliability power connection on printed circuit boards. The 1.25 mm pitch allows for dense pin arrangements while maintaining adequate spacing. Consider the 2 A current rating per contact when designing power traces. The vertical orientation facilitates direct mating with corresponding pins or cables above the board.

Part Context

This connector belongs to the Harwin Gecko-SL family, designed for space-constrained power applications. The series emphasizes robust mechanical retention and electrical stability. The G125 prefix indicates the 1.25 mm pitch standard. As a power-to-board solution, it bridges power sources directly to main circuitry efficiently.

Replacement Considerations
