Overview
The Harwin G125-FS11005L0R is a Gecko-Latch series power-to-board connector featuring a 1.25 mm pitch and 10 positions in a 2-row configuration. Designed for vertical surface mount technology (SMT) installation, it utilizes solder termination. The socket contacts are gold-plated copper alloy rated for 2 A current and 250 V/450 V voltage. Constructed with polyamide insulation, it operates between -65°C and +150°C with an insulation resistance of 10 GOhms.
Feature Summary
- Vertical SMT mounting for compact board integration
- Gold-plated copper alloy sockets for reliable conductivity
- Polyamide housing ensuring high thermal stability
Applications
- Power distribution on dense PCBs
- High-reliability industrial electronics
- Automotive control modules
Procurement Notes
Verify the specific suffix 'L0R' against the manufacturer's latest datasheet to confirm reel packaging and RoHS compliance status. Ensure the ordering code matches the required 1.25mm pitch and 2x5 configuration. Cross-reference the component marking with official Harwin documentation to prevent counterfeit substitution during procurement.
Selection Notes
Select this component when vertical space is constrained and surface mount assembly is required. It suits applications needing robust power connections with 2A per contact capacity. Verify that the PCB footprint aligns with the 1.25mm grid and that reflow soldering profiles accommodate the polyamide material limits.
Part Context
This part belongs to the Harwin Gecko-Latch family, designed for high-density interconnects. It complements male headers like the G125-MV series. The series emphasizes secure latching mechanisms and miniaturization for modern electronic systems requiring reliable power delivery in small form factors.
Replacement Considerations
Direct substitutes within the same Gecko-Latch series include variants with different row counts or pin lengths. Check for equivalent parts from other manufacturers offering 1.25mm pitch SMT female connectors with similar current ratings and thermal specifications.
