G125-MV21605L2R

Overview

The Harwin G125-MV21605L2R is a male DIL vertical through-board connector from the Gecko-SL series. It features a 1.25 mm pitch and is designed for surface or board mounting applications requiring robust electrical connections. The component utilizes gold-plated phosphor bronze contacts to ensure reliable signal transmission and low contact resistance. Rated for 2 A current and up to 450 V voltage, it operates within a temperature range of -65 °C to +150 °C. The housing is constructed from polyamide (PA) with UL 94 V-0 flammability rating. Packaged in tape and reel format, this connector supports automated pick-and-place assembly processes.

Feature Summary

• Vertical dual-in-line male configuration for through-board mounting
• Gold-plated phosphor bronze contacts for enhanced conductivity
• Polyamide housing with high thermal stability and flame retardancy
• Tape and reel packaging compatible with automated assembly

Applications

• Industrial control systems requiring high-density interconnects
• Automotive electronics modules needing reliable power distribution
• Consumer appliance mainboards with strict space constraints
• Telecommunications equipment utilizing standardized connector interfaces

Procurement Notes

Verify that the specific order matches the G125-MV21605L2R part number exactly, as suffixes indicate critical variations in packaging and contact plating. Confirm compatibility with existing PCB footprints and mating connectors within the Gecko-SL ecosystem. Ensure storage conditions maintain the integrity of the gold plating and polyamide housing before installation.

Selection Notes

Select this component when a vertical male connector with a 1.25 mm pitch is required for through-board applications. Consider the 2 A current rating and 450 V voltage limit against system requirements. Evaluate the tape and reel packaging necessity for high-volume automated production lines versus bulk or cut-tape alternatives for prototyping.
