Overview
The G125-FV11205F3R is a Gecko-SL series power-to-board connector manufactured by Harwin. It features a 12-position female socket configuration with a 1.25 mm pitch. The component utilizes vertical through-hole solder termination and reverse fixings for secure board attachment. Rated current is 2 A, with voltage ratings of 120 V and 240 V. Operating temperature ranges from -65 °C to +150 °C.
Feature Summary
- Vertical through-hole mounting with reverse fixing mechanism
- Dual-row 12-position female socket interface
- Gold-plated phosphor bronze contacts for reliable conductivity
Applications
- Industrial control systems requiring high-reliability interconnects
- Automotive electronics applications
- General purpose circuit board connections
Procurement Notes
Verify the specific suffix 'F3R' against official Harwin documentation to confirm the reverse fixing configuration and tape-and-reel packaging format. Ensure compatibility with mating male headers within the same Gecko-SL family. Cross-reference RoHS and REACH compliance status directly with the manufacturer's latest declaration before procurement.
Selection Notes
Select this component when vertical orientation and secure mechanical retention via reverse fixings are required. The 1.25 mm pitch allows for dense board layouts. Verify that the 2 A current rating and 150 °C thermal capability meet the specific application's electrical and environmental demands compared to standard surface mount alternatives.
Part Context
This part belongs to the Harwin Gecko-SL range, designed for compact signal and power transmission. The series emphasizes high reliability in harsh environments. The G125-FV11205F3R specifically addresses needs for robust vertical interconnects with enhanced mechanical stability through its unique fixing design.
Replacement Considerations
Compatible substitutes include other Gecko-SL vertical sockets with matching 12-position counts and reverse fixing mechanisms. Ensure mating pin headers share the same 1.25 mm pitch and contact plating specifications to maintain electrical continuity.
