About

JST 1.25mm GH Series Connectors — Miniature Wire-to-Board Interconnects for High-Density Designs The JST GH series at 1.25mm pitch represents the pinnacle of miniaturized wire-to-board connector engineering. Designed for the most space-constrained electronic assemblies, the GH series delivers exceptional contact reliability and mechanical retention in a form factor that enables unprecedented connector density on compact PCBs. From cutting-edge wearable devices to sub-250g drones and precision medical instrumentation, the GH series is the connector of choice for engineers pushing the boundaries of miniaturization without compromising on performance or serviceability. Key Technical Advantages 1.25mm Ultra-Miniature Pitch: Achieves maximum connector density in the smallest possible PCB footprint, enabling multi-channel signal and power routing in devices where every square millimeter of board space is critical. Positive-Latch Housing: Despite its miniature size, the GH series features a positive-retention locking mechanism that prevents accidental unmating under vibration and handling, maintaining reliable contact integrity in wearable and portable applications. Gold-Plated Contacts: Premium gold plating delivers superior corrosion resistance and ultra-stable low contact resistance across thousands of mating cycles, ensuring long-term signal fidelity in sensitive analog, digital, and low-level sensor circuits. High-Temperature PA66 Housing: UL94 V-0 rated nylon housing withstands reflow-adjacent temperatures and continuous operation up to 105°C, maintaining dimensional stability and dielectric integrity in thermally demanding environments. Wide Pin Count Range: Available from 2-pin to 15-pin configurations, supporting diverse signal and power routing requirements across the full spectrum of compact electronic assemblies. Ultra-Fine Wire Compatibility: Accepts 28–32 AWG wire, compatible with precision GH-series crimp tooling for clean, reliable terminations in high-dens
