GQ0A021691GT

GQ0A021691GT Description

The GQ0A021691GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each rated at 1.69kΩ ±2% tolerance, with a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and durability in demanding environments. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for circuits requiring reliable power dissipation. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space efficiency.

GQ0A021691GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in multi-channel systems.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in elevated temperatures.
• Robust Ceramic Case: Enhances thermal conductivity and mechanical strength compared to plastic alternatives.
• Surface-Mount Gull Wing Terminals: Ensures secure soldering and compatibility with automated assembly processes.
• Compact QSOP Package: Ideal for space-constrained designs, with tight tolerances (±0.1mm length/height, ±0.2mm depth).

GQ0A021691GT Applications

This resistor network excels in:

• Industrial Control Systems: Precision voltage dividers, feedback networks, and signal conditioning.
• Medical Electronics: High-reliability circuits in diagnostic equipment where stability is critical.
• Telecommunications: Impedance matching and termination in RF/module designs.
• Test & Measurement Equipment: Calibration circuits requiring low TCR and tight tolerance.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems where ceramic robustness is preferred.

Conclusion of GQ0A021691GT

The GQ0A021691GT stands out for its combination of precision, isolation, and ceramic-packaged durability, making it a superior choice over plastic-cased networks in harsh environments. While not PPAP or automotive-qualified, its thin-film technology and 2% tolerance ensure accuracy for industrial, medical, and telecom applications. The QSOP form factor balances performance with space efficiency, ideal for modern PCB designs. Engineers seeking a reliable, high-temperature-resistant resistor network will find this model a compelling solution.
