GQ0A0129R4GFT Description

The GQ0A0129R4GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 29.4 Ω resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.64mm terminal pitch facilitates high-density PCB layouts.

GQ0A0129R4GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, ideal for multi-channel isolation.
• Ceramic Case: Enhances thermal conductivity and mechanical robustness in harsh environments.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability under thermal stress.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm footprint optimizes space-constrained designs.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
